What are /r/sexover50's favorite Products & Services?

From 3.5 billion Reddit comments

Background for anyone who doesn't know or remember: I found out a month ago I have E.D.

Still taking vitamins but not feeling any difference. Doctor's appointment on Thursday and I'll discuss it with him then and see what he says. In the meantime I bought The Penis Book, written by a urologist. Interesting stuff about how it works (both how it's supposed to and when it doesn't), what can be done, etc. Reminds me that I have to make a modification to my vitamin regimen.

I got some positive feedback from fellow Redditors here the last times I've mentioned this, and want to publicly say thank you and I very much appreciate the encouragement and support.
