Too embarrassing for the doctors

I have an issue that I'm struggling with that I'm too embarrassed to see a doctor about. I've been in a fully committed relationship for the past year with a great guy. Since the start, everything between us has been great. Dreamlike really. The only issue we've had is sex. He isn't my first. In fact, I've been with plenty of guys, as a top and bottom and I've never had an issue before. I've always been sti free but not always practicing safety sexs. There's been loads of mouth stuff too. But with this one guy, things are different. Since the start, sex with him has always burnt. Like, when I put it in, it's like tight fire. Every time, without exception. I don't get it. I've even tried it with a couple other guys while we've been together to see if it's me but it's been fine! So it must be him right? Not only that, but my 'tip' has started to go slightly green. Any help would be greatly appreciating.

:-S (A) Starting to sound really bad that something down there is going green. Doctors have seen a lot of cases Hopefully you are using protection

I get how seeing a doctor is embarrassing, but think of it this way. Love yourself enough to get tested or checked. People will judge any and everyone from a homeless whore to the pope himself.. Who cares let them judge. At the end of the day its your body and your life. Life is not short but it is precious, got as a couple or go alone to a clinic, besides confidentiality is a must so your business is private. Hope this helps

Thanks guys but it's all sorted. It fell off.
