Strap-ons and UTIs

QUESTION:
My girlfriend and I have a great sex life except for one little problem. Whenever she fucks my cunt
from behind it the strap-on I always get a bladder infection the next day. She fucks me other ways and
we're all good...just doggy is the problem. What are we doing wrong?

ANSWER:
Dear WTBO:
Sorry to hear you’re getting repeated bladder infections (aka UTIs), particularly as a result of something
as yummilicious as doggy-style sex! Their timing suggests they’re not due to common causes like wiping
back to front when you go to the washroom or poor diet.

UTIs are caused by bacteria getting in your urethra, the tube that connects your bladder to the opening
you pee through. What you may not know is doggy style, despite its many delights, is a position where gravity is
not your friend on the UTI front.

So where does the bacteria come from? Unless you wash your vulva with hypo-allergenic soap and your
girlfriend her hands, or wears gloves, before touching you or her cock, any bacteria around mixes with
your natural juices and any lube you're using, including the lube on your condom. The vigorous and deep
thrusting that ideally comes along with doggy-style means this bacteria-laden brew is likely to drip its
way down into your urethra, which is conveniently located between the opening to your vagina and
your clitoris.

Another source of irritation could be the lube you’re using. Oil-based lubes (Vaseline, body lotions,
baby or other oils) greatly increase the chance of vaginal infections. Consider also trying a water-based
glycerin-free lube (Hydra Smooth, Liquid Silk, Maximus, Slippery Stuff) rather than one with glycerin (Astroglide, Eros Water Formulation, K-Y, Foreplay, ID, Sex Grease, Wet), as for some folks with a vag glycerin triggers infections.

Silicone lubes (Eros, Eros Woman, ID Millennium, Wet Platinum) are an option, as are non-glycerin
water-based ‘natural’ lubricants (O'My, Probe, Sylk), which contain natural ingredients. Just because
something is natural, however, doesn't mean it doesn’t irritate! Whatever lube you try, ensure it’s not
flavoured if you’re using it right on your vulva, as they often include sugar or sugar substitutes that
cause or aggravate infections. The best way to find the right lube for you, as it varies widely from vag to
vag, is to ask at a higher quality sex store for samples of lubes and condoms to try before spending lots
of money on ones that might not work for you.

Finally, a tried-but-true UTI prevention tip is peeing after sex. Even the smallest amount of urine can
flush out bacteria trapped in the urethra, so it’s a good post-doggy habit to get into, like brushing your
teeth after savouring a nice big long peppermint stick!

Kisses,
Leah
