Does anyone know what causes men to have multiples or how to achieve them?

Nobody knows out there?

I was watching for a response because I want to know how to achieve this

I have seen stuff out there you can buy but I dont know if that stuff actually does any good

most of that kind of stuff is questionable

Yeah I figured it as much

OK I've held back on putting this out here - but it does relate to your question BWG, but may not apply to you personally or others here who are not interested in anal stimulation (from your girl, wife, or boyfriend):

I have been with a guy three times who has had multiple, one-closely-followed-by-another ejaculation from having his prostate bumped so much during anal sex (could also happen with a toy, you know, such as a dildo or an "anal stimulator"). He came 5 times the first time we were together, 4 times the next, and 5 times again at our last rendevouz! Amazing -- he was as incredulous as I was -- Also made me feel proud! LOL.

So, multiples - I don't know otherwise. I met a guy who also came twice in a row on the same erection, and without much additional stimulation. Must just be an individual person thing.

Wish I could do that!

Wow! I bet you both were proud!
