Hi.. I am 49 yrs old and for the last couple of months I have been gradually losing my erection... at first it was just now and then it would happen i.e.. I would find even though I was horny it would take a while to get a full erection, but gradually it has gotten to the stage I can't get an erection at all during foreplay and sex. Am not sure if its just the more I think about it the worse it gets, the reason I say this is because I still wake in the morning with an erection... its definitely not a problem with my wife, even though we have been married 30 yrs now she is still a very sexy woman to me, we do and always have done all the usual foreplay stuff, massage,oral, sexy videos, fantasies etc. etc. and I feel I am letting her down at the minute. We are still having sex using all of the above including a vibrator and she still manages to make me come even without my erection but,I WANT IT BACK... I NEED IT BACK... can anybody help me?. ps. Tried viagra and instead of getting a bloodrush to my penis it went to my head and gave me a terrific headache
