I am 31 and he also tried to be my boyfriend. He's a great guy, but he is not focused on an age group that is suitable for him. All his friends are under 35. I love him as a friend and don't want to hurt him. While some younger men are attracted to older men, they are few and far between.
Most gay men prefer to be with guys around their old age.
Boyfriends aren't hard to find, unless of course you will only date Brad Pitt. Brad Pitt is very hard to find and, as Gwyneth can tell you, even harder to hold on to. Last time my boyfriend was in town for the weekend, I opened his travel kit to borrow some allergy medicine. I couldn't help but notice that his previously full box of condoms was missing several. I didn't say anything.
