During the summer me and my boyfriend went on a trip to Canada. We rode jet skis twice and our "parts" were basically rubbing all over the seat of the jet ski. A day or so after that we had sex. I noticed little painful bumps that look like pimples on my outer labia and on my butt. I just thought it was something on the jet ski and I didn't worry about it. My boyfriend didn't have any on him. It went away in a week or so but when we got home we had sex again and there was one bump on his penis and a few in the surrounding area but he said it didn't hurt and it wasn't bothering him. Mine went away but sometimes I'll get a few again but they go away in a few days.however they have gotten less and less in number when they do re appear. Right now I only have one on my buttcheeks lol. But I'm wondering if it's an STD or just something I contracted from riding the jet ski. My boyfriend is the only person I have sex with and I'm the only one here has sex with and this was never a problem before we rode jet skis. I'm also still a teenager and I don't want my parents to know if it's an STD but I do understand it will have to be treated if it is. I've been to the gyno but for other reasons and I always forget to mention this. Someone please help lol
