Have you ever laughed during sex?

Ki
I'm not talking the "omg he has a tiny penis" or the "I'm sorry my vagina did that" kind of laugh.
I had the oddest experience and I wanted to know if I'm the only one whose dealt with this or not. 
So, my fiancé and I had just started getting it on when I started moving, lifting up my legs, which was dumb because I always end up getting hurt that way, buuuut this time when he hit wherever it is in the batcave, I started laughing. 
I started laughing hysterically, started tearing up, couldn't breathe, insane burst of laughter for a few minutes. 
It didn't hurt or anything like it usually does, and that's why I'm wondering if anyone else has experienced anything like this.
So ladies, have you ever been having sex & a man hits something in there && you started laughing?? 
I totally got funny boned.
