Me and my friend are going for a sleepover soon, we are both 12 and he always makes gay jokes and humps me sometimes, I want to do more but am scared to ask, what should I do?
I found that keeping a light attitude (such as joking and talking together about sexual stuff) can justify your own rising sexual excitement, to the point that you can just tell him that talking about it has really "turned you on" or made you feel like masturbating. Then say something like "I've just got to. I'm gonna do it!". Perhaps you turn away from him or pretend to try to hide it from him as you pull out your own penis and begin to masturbate right then and there, as if you don't care if he is there or not. I suspect that he will want to see what you are doing and that will open the door to sharing the experience. My own friends with whom I shared this pleasure would often say "you are not!", daring me to actually masturbate as i said i was going to do. Of course I then had to prove that I was indeed masturbating as i had claimed, and that always opened the door to watching each other -- and more.
