How do you know if you orgasm? People always say you'll just know, but I'm pretty sure I did last time I had sex, but it wasn't like a super intense thing like I see most people describe. I mean it was nice obviously, but nothing like super intense. I can't orgasm with penetration alone. My partner is great and I enjoy myself every time we have sex, so it's not that I have horribly bad sex or anything. I've read that some women just don't orgasm, but I've never met anyone else that doesn't.
