Yes, hygiene can take a dive as you age. Believe it or not you may not feel like going for a run, and working out. You can get illness that come with age and they can make life difficult.
I am with robdar, I like intelligent men. I never dated anyone b/c they were a pretty boy. I always felt attracted to the smart guys.
yes the antidepressants can cause some problems but not all of them cause ED. Seeing a doc and maybe a trial on Wellbutrin might help. It does not usually cause ED. BTW, the doc will treat you individually, not as a couple. Most of the herbal things for depression are useless ( for clinical depression ) but St.Johns wort could help him with mild depression, but don't take it for bipolar( it can throw you into a manic episode). don't discourage our hubby from seeking treatment b/c of your sex life-You won't have one anyhow if he's that depressed. http://en.wikipedia.org/wiki/Bupropion

about the meds only
http://www.crazymeds.us/ The folks on the crazyboards are very nice and will help you sort this out. No doctors but patients with lots of experience and they can relate their experiences . The crazymeds.us site is amazing for info on meds but the site is not really for support except meds. So there you go, some links to help.
