I don't have a T anymore but I did have a male one and I thought this would be hella hard and awkward but he was so good with it, it was not bad.

I don't have sexual experience, but that's a whole issue in itself and I had a long struggle with something related to sex that was basically an addiction and we did get graphic but I wrote it out. I had him read it, then we talked about it from there

So maybe write stuff out... and remember to pace yourself. It's ok if it takes a long time. I am glad you are bold enough to talk about it with him though.
