I feel bad for hubby though - He loves doing it - And I know that what he is doing has to be amazing - because
I see porn stars having earth shattering orgasms from guys who are doing to them what my guy is doing to me...
You do realize porn stars are acting, don't you? Porn is great for giving ideas, but do not compare what you and your husband do to what the script tells the actors to do and how to react.
If you did have more experience with other men, comparing your husband's performance with someone else's wouldn't be fair to either of them.
Joy and Judy have said about all there is to say. I will add stop pressuring yourself to enjoy a sex act you aren't comfortable with.
Just something to think about
: I will also say that if your husband is mimicking what he has seen in porn movies, his technique may not be the best way to pleasure you. It might be something to discuss with your husband if you want to see if there might be a compromise.
Sex in a committed long-term relationship is as much about communicating as it is the acts. Talking about 'likes', 'dislikes' and 'maybe tries' can help keep a couple from letting their sex life stagnate.
If you are both happy and satisfied, does it matter what other people think?
