So I'm a young bi boy in a relationship with an older daddy. It's very satisfying for both of us. He is very dominant and I am very submissive. A strong aspect of this is that daddy has a much bigger penis than me, and I really am sexually excited by this and enjoy my smallness compared to him. Daddy's teasing me about our big/small penis dynamic is part of the excitement.

Is this a problem?? Is it OK to enjoy sexual humiliation along these lines? Have other people done this? I am not experienced with many kinds of sex and just kind of fell into this. And yeah, I think it partly has to do with feelings about my father. I would clarify that I have only been exploring my feelings about my father in sexual ways that have been healthy and growthful for me.

Also: is there a risk of STD transmission when I receive a facial?

Thanks.
