I've just started a relationship with a wonderful new partner. The sex is great: she came four or five times the first time we fucked, and she takes absolutely all of me (and would probably take more if I had it). However, she got a yeast infection after the first weekend, and a UTI after the second weekend. This continues a disturbing trend, which is that when I start a new sexual relationship, frequently the woman will get a UTI soon after. Fortunately, it rarely recurs after the first time, but I'd rather not cause that sort of problem! -I've always used a condom, so it's probably not germs I'm giving her. -I use lots of lube, and we stop several times along the way to reapply. It's definitely not a dryness problem. -I'm big, but there are lots of bigger men here. (I'm 7-8" long, 6.5" around.) -I tend to last a long time...30-45 minutes is normal. Is this a common problem here on the LPSG, or am I just having bad luck?
