Why do I get hard so fast and for no reason

[Greedy]

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,,,,,,,,
