I just purchased a STAMINA TRAINER - PENIS TIP MASSAGER. I'll let you know if it works. I have a SASHA GREY UR3 DEEP THROAT POCKET PAL MASTURBATOR, and it works great (as long as you use Astroglide). See pictures (from "shop sex toys"}
My opinion? It's simple. Too many STD's out there these days. In the 70's it was common to have a lot of girl friends. Now, I think you need to get blood tests before sex. You just have to be sure, you know?
I am a widower now. Been married 2 times before my last wife, so it's not easy sleeping by myself. My friend says, "go out and meet someone". I say, "yeah, at my age"...lol! So, I'm 60 years young now, but still like to get that high from an orgasm.
Have fun, everybody!
