Oh thank God this is fairly normal! Haha Yeah, I was in bed with my friend and she gave me the most INCREDIBLE time! Afterwards my legs were shaking like effing mad, and the rest of my body seemed to be shaking a little bit too, and after that I noticed whenever I get a reeeally good orgasm, it takes quite a while to recover!
Haha I know! Maybe it's the universe' way of making up for the pain of giving birth or something? lol
