Dylan does not have a heterosexual style of behavior. He does nothing to court women, he is fixated solely on his mother. He's sitting on his mother's lap. Why? Because he wants to replace his mother. He subconsciously wants to take her place in life. Dylan pays Aiden. Because he subconsciously wants Aiden. He tries to tame it, instead of coming into conflict with it, like a male.
Dylan is a typical 'Puer Aeternus' - the Eternal Youth of Marie-Louise von Franz .
Well, Dylan would be the first gay who jerks off over naked women ...
