A man who's still a virgin, has a very very rare disease which allows
him to only have sex seven times in his life. After he has used up all
the seven chances, he will never ever be able to have sex again for the
rest of his life... and so far, he has wasted two times on 'self
gratification'. Now he only has five times left, and he wants to choose
carefully and save himself for that someone special...but at the same
time he desperately wants to lose his virginity...
