will this turn into a bad thing?

[Kontroll]

before i masturbate, i usualy put my dick on some kind of hard surface, and push down on my dick with my fist. i find i can masturbate longer when i do that, but will it hurt my dick eventualy if i do that for a while?

[Ender]

Um... ouch? Yeah dont do that.

[Kontroll]

i dont do it hard so it hurts, but just lightly
idk y, but it helps me go for longer

Well thats the first time I've ever heard of any one doing something like this. I personally wouldn't do such a thing to my penis as that just sounds like it would hurt or cause damage. I'm not sure if that will cause long term or short term damage, The best thing to do is not to do it all.

I sometimes do that...just like a hard pressure on your dick right? Yea it makes it better for me and i've had no problems so far, as long as you don't go too far with it

[The_Average_Kid]

[Jerkface327]

[The Dark Lord]

I've never heard of doing this, Its up to you but I'd stop it cos it sounds painful
