Sometimes, when having a really good time, I laugh, yes. I think sex offers this kind of no barriers space, and the sudden awareness of that can make you be a bit hysteric, or euphoric. Great spelling I am afraid.
A couple of girlfriends found themselves laughing while having sex with moi. For some reason, they found it highly embarassing... although they couldn't help doing it!
I think it's alright. I wish I could do it more often.
