He is a HOMO because he just fucked himself,so it cant be masterbation because he dident wank he just fucked himself!

He'd exist on a different timeline, I think. Making him kind of a different person? I don't know, but it sure as hell sounds fun. Er, I mean, gross... yea.

Technically, it is both! Here is the homosexual argument. Masturbation can only be performed by a single individual on themselves, but they do not have to be alone. So, having another individual, including your future self perform anything sexual on your historical self is homosexual.

It is homosexuality.. While it's him in the past, it's two separate bodies getting pleasure.

I say all of the above, plus depending on what age his previous self is, it might be considered statutory rape.

14 year old me had hair down to my back and a very feminine body despite being an athlete. I think I would have looked good in a dress...this is gay in the weirdest way. Homosexuality, hands down.

Actually, .Homosexual because it's another body and if I give a handjob to myself in the past , I will experience it in the past and not the future thus not stimulating my future self, rendering the action worthless except probably loving my own self and gender and wanting to please him through some kind of foreplay.

:D I'm so weird
