If I keep getting yeast infections or BV, what could be causing it (sex, condoms/lube, period products, workouts, stress), and what’s the best plan to prevent it without messing up my vaginal microbiome?

Recurrent yeast infections or bacterial vaginosis (BV) usually mean your vaginal microbiome is pissed off, not that your body is “gross.” Triggers can include unprotected sex or semen, new partners, fragranced soaps or wipes, certain lubes or condoms, tight synthetic underwear, staying in sweaty workout clothes, antibiotics, high-sugar diets, unmanaged stress, or hormonal shifts (like birth control or luteal phase changes).The best prevention plan is: get properly diagnosed (swab + lab, not vibes), treat fully, then protect your microbiome. That means: avoiding douching and scented products, using pH-friendly lube and condoms, wearing breathable cotton, changing quickly after workouts, managing blood sugar and stress, and sometimes using targeted probiotics or boric acid (with medical guidance). Your doctor should help you map triggers, not just throw another cream at you.Want to pick apart every infection, product, and hookup to see what’s actually triggering flare-ups?

Why you keep getting yeast infections or BV and how to prevent them without harming your vaginal microbiome

First: yeast infection vs BV — what’s the difference?

They both mess with your week, but they’re not the same beast.Yeast infection (vulvovaginal candidiasis)

• Cause: Overgrowth of yeast (usually Candida albicans).
• Symptoms: Intense itching, burning, thick white “cottage cheese” discharge, redness, swelling.
• Smell: Usually mild or none.

Bacterial vaginosis (BV)

• Cause: Overgrowth of “bad” bacteria and drop in protective lactobacillus.
• Symptoms: Thin gray/white discharge, strong fishy odor (especially after sex), mild irritation at most.
• Smell: Major. Like, room-clearing sometimes.

You can also have both at once (rude, but it happens), which is why a proper diagnosis matters.

How your vaginal microbiome works (and why it keeps flipping out)

Your vaginal microbiome is a squad of mostly lactobacillus bacteria that:

• Keep your pH acidic (around 3.8–4.5).
• Produce lactic acid and hydrogen peroxide that shut down invaders.
• Compete with yeast and “bad” bacteria for space and food.

When that balance gets wrecked—pH rises, lactobacillus drop—BV can take over. If your immune system or hormones shift, or you disrupt the area with products or friction, yeast can overgrow too.Hormones matter here:

• High estrogen (around ovulation) supports lactobacillus and can stabilize your microbiome.
• Late luteal phase (before your period) can mean immune changes and more yeast flare-ups for some people.
• Birth control can either help or hurt, depending on your body and method.

Common triggers for recurrent yeast or BV

Let’s be honest: your vagina is probably reacting to your lifestyle, not plotting against you.Sex & partners

• Semen is alkaline and can temporarily raise pH, which encourages BV in some people.
• New or multiple partners = new bacteria your body has to adjust to.
• Unprotected sex can make BV more likely; some STIs also mimic BV/yeast symptoms.

Condoms and lube

• Spermicidal lubes and non–pH balanced products can disrupt your microbiome.
• Flavored or scented lubes = sugar and chemicals that yeast love.
• Latex sensitivity can cause irritation, which opens the door for infection.

Period products

• Scented pads, tampons, or wipes = unnecessary irritants.
• Leaving tampons in too long can mess with pH and bacteria.
• Some people find discs or cups shift their pattern if they’re not cleaned properly.

Workouts & clothing

• Living in sweaty leggings or thongs = warm, moist, low airflow heaven for yeast.
• Tight, non-breathable underwear keeps moisture trapped.

Stress, diet, meds

• High stress = high cortisol = weaker immune defense.
• High-sugar diets can feed yeast over time, especially if you’re already prone.
• Antibiotics wipe out good bacteria, including lactobacillus, which triggers BV or yeast overgrowth.

If your experiences don’t fit one neat category (“I get BV after sex but yeast before my period and wtf does that even mean?”), you’re not broken—you’re complex. Walk through each flare-up, cycle phase, product, and partner with Gush and we can help you see the patterns your doctor might be missing.

How your menstrual cycle can influence infections

Each phase can shift your risk slightly:

• Follicular phase: Rising estrogen strengthens the vaginal lining and supports lactobacillus. Some people feel most “stable” here.
• Ovulation: Peak estrogen, lots of slippery mucus. Generally protective, but more sex during this time + semen can trigger BV in some.
• Luteal phase: Progesterone dominates; immune response can drop a bit. Many notice yeast infections right before their period.
• Menstrual phase: Blood raises pH (less acidic), creating a window for BV or yeast to flare, especially if you’re already prone.

Tracking when infections hit in your cycle is powerful data to bring your doctor.

What a smart prevention plan with your doctor should look like

Your doctor’s job is more than re-prescribing the same cream. Ask for:

• Proper testing: Swabs for BV, yeast type, and STIs—not just a glance and a guess.
• Culture if recurrent: To see which exact yeast species and which meds it’s resistant to.
• Blood work if needed: To rule out diabetes, immune issues, or hormonal imbalances if infections are constant.
• A real prevention plan: Not “Here’s another Diflucan, bye.”

Questions to use:

• “Since this keeps happening, can we dig into why instead of just treating it again?”
• “What do you think is triggering this—sex, products, hormones, meds?”
• “Is there a long-term plan we can use for suppressing BV/yeast safely?”

Protecting your vaginal microbiome without going feral on products

Think: less disruption, more support.Daily habits:

• Wash the vulva (outside) with warm water and a gentle, unscented cleanser only if needed. Never inside.
• No douching, scented soaps, vaginal sprays, or “feminine hygiene” nonsense.
• Wear breathable cotton underwear; skip thongs for all-day wear if you’re prone to infections.
• Change out of wet swimsuits and sweaty leggings ASAP.

Sex habits:

• Use pH-balanced, glycerin-free lube if yeast is an issue.
• Consider condoms, especially if semen seems to trigger BV.
• Rinse off gently after sex if you’re sensitive, but don’t scrub or douche.

Products to consider (with medical guidance):

• Vaginal probiotics: Some lactobacillus-based products help maintain balance, especially after antibiotics.
• Boric acid suppositories: Can help prevent recurrent BV or yeast in some people, but should be used with a plan, not randomly.

Cycle-informed prevention strategies

Because your hormones aren’t static, your prevention doesn’t have to be either.

• If you usually flare before your period, talk about using a short preventive course (like boric acid or a mild antifungal) in your luteal phase.
• If sex is your trigger, focus prevention around high-activity weeks: condoms, pH-friendly lube, gentle post-sex care.
• If antibiotics blow things up, ask for a plan that includes probiotics or preventive treatment during/after the course.

Bottom line: recurrent infections aren’t a “you’re dirty” problem—they’re a “your ecosystem is sensitive and needs respect” problem.
