Boyfriend and I had sex for the first time on Friday, well I use the term sex loosely, he gets hard then before penetration he goes soft (sometimes during) and then says it feels like he needs to go to the toilet, every time it happened, then would go to the toilet. (which was a every single time) He is very healthy, eats well and very built so certainly not physical health, but I'm not sure what's wrong with him? Is it something that's happened to any of you? Or should I be a bit worried and get him down to an STD clinic?
