As long as the kid consents, what's the problem? I could claim you are too immature to know what's best for you, but that's bullshit. There's no such thing as 'too immature'. We all make mistakes we regret later in life--no matter how old we are. Maybe the kid would regret it, but maybe he wouldn't. Maybe he would look back fondly on that first time he explored his sexuality with an older male.
Now, I'm a hetrosexual male, but I disagree with age of consent laws because I don't think the government has a right to tell people they are too immature to make decisions regarding their own body. And yes, I consider children to be people--unlike the vast majority of adults in the world.
