You might be right. I haven't had that checked. It's the first time it's been like that. But yes when I cross my legs for too long it falls asleep and tingle, same as being in a sex position such as reverse cowgirl that requires a lot of leg strength. That would such though if it were a circulatory problem. I've always been very tense. My body in general which I think has a lot to do with me being sensitive all over and have no problem cumming easily. It's quite a mystery. P
