I have tried it... After much coaxing.
We went into it gradually, FIRST, he had
me do it to myself while I was masturbating, then he would mention it occasionally, as something he would want to do, but not force me to. There were other times where he would finger me and slip a finger in.
Then, I said I wanted to try it. we did, but it hurt way too much and we settled for me blowing him
After "trying it" a few times, we went back to the gradients, even using a vibrator, (which I LOVED) till he could fuck me. It was good for him, quit a bit painful for me, but I think I could get used to it.
