I'm really confused. Around 1:30am this morning I had sex with my gf of over a year. We've been having unprotected sex for nearly 8 months. While going at it I pushed in pretty rough and rammed the tip into the very back of her. It kinda felt like I stretched the opening of my hole. It bothered me a bit an ending up being annoying enough for us to stop, so I didn't end up ejaculating. Then I woke up 6:45am and noticed that I had quite a bit of yellow creamy discharge coming from the tip. I rushed to used the bathroom and everything seemed to work fine, no burning or anything. Two hours later and I can see some more discharge inside the shaft when I squeeze the tip. If it matter I'm a grower not a shower, I've never had something like this before, but I did have a UTI before. Any help would be awesome. I don't think it's an STD because of the time frame. But I don't know.
