Confused, and don't know what to do?

I'm a 37 year old guy, heterosexual, or so I thought.

I've just come out of a 14 year relationship, and I couldn't be happier. I was looking forward to single life again, but I don't know what it is that I want.

When I was a teenager, I had several gay encounters. It was really just experimenting, and even then I new I was straight. I enjoyed my experiences, but I was sure i preferred girls over men any time. But now I'm single again, I find myself wanting another gay experience. I'm looking at gay porn more, and girls don't interest me so much. But i'm still certain that I'm not actually gay, The idea of having anything more than a one night stand with a guy does not even begin to appeal to me.

I suppose my question is, Is it a good idea to go to a gay club or bar, and see what bites? It wouldn't be anything more than casual sex, so I'm not sure if it's fair on the guys who are looking for something more. I'm not even sure I would actually go through with anything if it came to it.

With much respect to the Gay community, i welcome your thoughts.
