I am wondering why you think you are going to be relegated to sex toys. A few years ago while I was in grad school I rented a flat from an older guy, say 60 ish. He was good looking, a few extra pounds - sort of average but very pleasant company. The guy was getting more dick than any five hot twinks I knew! He found a "groove" as it were. At the time, he posted on Craigslist for anon married guys - no strings hook ups. DUDE! Seriously, he was getting pounded some times three times a day. No exaggeration. He also had a bevy of first time teens who had daddy issues - my point is - maybe you are tossing in the towel a bit prematurely?
Sex toys are fun I suppose, but hardly a replacement for a hot human. But if you are intent on such things - there are a lot of vids on Pornub https://www.pornhub.com/view_video.php?viewkey=ph5604d294c292d with guys loosing their shit on chatterbate, I think it's called Ohmibod? They seem to really REALLY love it. Nipple thing - not sure.
