I recently started gyming as I have this new MMA slash personal trainer slash slash slash boyfriend that everyone wants, I decided to shake off a few ks at the gym and started trying abdominal leg raises (if thats what its called?!) anyway, so I try it and I get this feeling in my muscles I can't really place, but it felt horrible yet sooo good. I decided to try it again the next day, the feeling was there again and I was wondering in the back of my mind if it is the same feeling that I get when I am about to have an orgasm. I stopped using the thing but tonight my trainer said I don't have a choice , she obviously didnt know about the feeling I get, just as they walk away to let me finish my last set it hit...I HAD AN ORGASM, RIGHT THERE AT GYM!!! I just let out a yelp, they all looked at me, wondering if i was okay...little did they know!
