Hatter saidPersonally I always feel like a creeper when a fairly younger guy has his attention on me. [No, there is no logic to this at all, just one of those things...]
Let me provide some logic, if I may.
When we're talking about a young teen, as in this case 15, to have anything sexual to do with him is not only criminal in many jurisdictions, but also predatory and unethical, a black mark against all gay men.
But let me expand this to both girls and boys, because most pedophilia actually happens between little girls and straight men.
Childhood is a special and magical time. A time of fantasy and toys, make-believe and imagination. The realities and cares of the adult world are years away yet. They play schoolyard games, believe in Santa, color with crayons, have dolls & action figures, play video games, have imaginary adventures. It's an enchanted bubble kids live in, that adults are supposed to protect, never burst, never intrude upon.
In due time these kids transition to being adults themselves. The age of 15 is not quite there yet, a time of bicycles & skateboards, Nintendos or whatever, becoming sexually awake but still not fully aware.
An adult does not take advantage of that. Not EVER! I don't care what the child says, this is just a child -- what do YOU say? You're the adult. Are you going to burst that bubble of childhood? I could never do that. I could never be that selfish, nor that conceited, which such an action implies.
So I hope the OP leaves this 15-year-old alone, no matter what the youngster wants. Kids ask for lots of things... have you never said NO to a kid's unreasonable request? I hope the OP's own desires don't cloud his judgment.
