Question about orgasm/squirting
So I have been having sex with my fwb a few times now, and every time we do it, I always feel like peeing/squirting (I'm not sure?). But last time I was having one of the most pleasure moments ever since I lost my V card, and I genuinely felt like i was going to cum but i'm too embarassed to release it because i dont like the the intense feeling of needing to pee, but at the same time it felt really good because his thing was hitting the right spot, which I have never experienced before with other people. I never had an internal orgasm before so idk what it feels like. How do I make sure that it's squirt and not pee bc I don't want him to be grossed out by the fluid?
