Can someone with erectile dysfunction have sex?

JermaineDuch asked:

I would like to know if it’s possible for someone with erectile dysfunction to engage in sexual intercourse, i.e., without using viagra or the likes. Is it possible for a someone with erectile dysfunction to perform vaginal penetration with a non-fully erect penis? Thanks for any help, guys!
I don’t know which one to believe, people. Some answers tell me I can’t while some others say I can. This is sad. TT.TT

why erectile dysfunction happens?

ED_guy asked:

i have been sexually active for last 20 years, i’m 38 now and since last 3 months i have lost libido and erection is not good quality & dampens off as i try to insert. I have been undergoing major life change like change of job and international location, child schooling and re-adjusting problems, problems with boss at work, i drink and smoke also heavy off-late.

i go to gym twice a week and do meditation/yoga but all in vain.

suggestions please.
i feel better erection in anal sex compared to normal vaginal sex.
