NOTE: I don't know you in real life, nor have I had any contact with you here. This means my comments can only be generalizations.
A lot of people want relationships. In fact, I'd say that most do.
You have to consider the environments you are searching for this relationship. Night clubs are not really the places to find one, just a fuck behind a dumpster (skip).
Another obvious answer is; how desperate are you for a relationship? That shows through as well. Oddly, though not surprisingly, you are more likely to get admirers when you are in a relationship than when you are looking for one. This is because you aren't in the desperate search mode. Don't be the woman (not calling you a woman, just using the scenario) that turns up on her first date wearing her wedding dress and yammering on about all the baby names she wants for her kids?
Here are some direct comments after looking at your website;
None of your pictures have you smiling, at least not real smiles. That's a turn off.
You should tidy up your website. Sadly, people will use any typos to automatically label you as "thick" and therefore dismiss you.
You seem hostile toward what you call the "gay scene". Most gays are not part of the media created gay scene, like you see in QAF or other series and movies. The real gay scene is pretty harmless and vanilla; ie going to movies and dinner with a group of friends.
You are 39, but you want someone a minimum of 4 years younger than you? This is so the 2 of you can experience life together? I don't see what life experiences you and an 18yo can do together that you can't do with a fellow 39yo. You want a young boyfriend, that is all there is to it. Experiencing life together isn't a real issue. I'm sure you'd agree if you were being honest.
