Urine. Bladder. Buttocks. Infection. Flow. Blood.
That wasn't so bad now was it? Urine is liquid gold. Your bladder may be small, but at least most of us have one. Are your buttocks too big, too small, or sweaty? We've all been there. How about infections?! They're so nice when they're over.
A lot of people I know are squeamish about these things. But being squeamish is not like being Amish. You can't claim it as a religion. All I can say is, "You're not alone, but get over it, and don't use that as an excuse." You shouldn't be afraid of talking about such things, or other sex related, and bodily related functions. That's life.
I'm not suggesting that talking about your urinary tract infection is the best wedding reception dinner conversation, but it shouldn't be something that makes you blush with the right crowd. And, I would suggest that that crowd is bigger than you think. People like to be helpful. Just watch me - Here's a sure way to urinary tract, menstrual, and even mental health: cranberry juice. It's like the miracle fruit. Loaded with anti-oxidant, free-radical blasting power, those tart little berries from the northern hinterland can pack the right punch in so many ways.
So, if you want to talk about your unmentionable problems, I have no problem with that. You should be tactful, but you shouldn't be embarrassed.
