My wife and I used to be unable to have intercourse for almost 3 years. Whenever we tried, she would feel pain and her muscles would contract, preventing me from penetration. However, since the last two months, we tried with lox 2% gel and her pain reduced. Subsequently, we are able to have intercourse without any lubricant now, although it takes a really long time for her to open up completely. The problem now is that, she does not feel any pleasure whatsoever, even when I am completely inside of her. What could possibly be the problem here?
