While I was exercising regulary I had the whole tantric thing pinned down, controlling ones focus and breathing to extend it, I've been doin kegels but had a problem.. was abit over eger and strained the muscle, it's just recently come good.
But when I was using the tantra method I was able to go for around an hour at the most. Those were good times, I love making love with Nay for long periods of time.. She's so wonderful. Hehe.. anyways.. I don't know about side effects, how about googling it..
