Why do I get hard so fast and for no reason
 

Ever since I have been taking my meds for pain and depression and PTSD I have noticed my drive for sex is not the same as my wifes. I want it all time for some days and then can go month's with out it. I am barely able to satisfy her when we do get in the mood together and sometimes I finish before she does.
Should I be concerned?

Pain meds kill a sex drive,,thats not a secret,,leave the meds alone for 3 days and your be back to normal,,its not uncommon at all,,,also i bet when your on them its still hard to maintain an erection,,semi soft,or premature goes off,,,thats the pain meds buddy,,,,stay of of them for about 3 days,,,watch what happens,,youll be ok,,,,,,,,

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.
