I can only have an orgasm with my legs straight and tensed. Is this weird?
The truth is a lot of people wonder if they look or act silly when they're feeling especially pleasured during sexual activity. And, the truth is that a lot of people do really different things- some people moan loudly, some scrunch up their face, curl their toes, even laugh! If you're comfortable being sexual with your partner, it's likely that it doesn't really matter all too much what happens when you orgasm. Regardless, try to focus on the orgasmic feeling you've just achieved, rather than your appearance. And, keep those orgasms coming!
