Hi Suma, I think the best thing for you would be Dr Betty Dodson, so just google dodson and ross, here you will find all the
answers you looking for when it comes to sex, its like all the questions you were affraid to ask, then there you will find all the answers.
Now if you think he has some kind of Ed erectile dysfuction, and dont want drugs then please come back to me, I'm on herbs and a hormone for ED.
