Bobber has a point with the pain meds but you also have to take into consideration that the idea of having sex while in pain isn't very appealing either.

I can tell you that foreplay goes a long way! The same with mutual masturbation. Yes, it's a shocking topic, and one that a lot of people chose not to talk about. If you are unsatisfied with your own sex abilities then by all means talk to your doctors about your meds. There are many options available that don't include taking seperate pills for pain anxiety and depression.

If you are more unsatisfied that your wife is not being fullfilled I would suggest extending the foreplay, maybe introducing toys, and using more than just intercourse. Women are very mental beings, and the act of sex although fulfilling is grealty enhanced in the knowledge that our partners are going to extra mile to pay attention to us and our needs.
