I HAVE a beautiful girlfriend and always thought I was straight but I’m sexually obsessed with one of my male friends. Am I gay after all?

I am 26 and I’ve been seeing my 25-year-old girlfriend for two years. I’m a plumber and she is a dentist, tall and beautiful.All my mates said I was punching way above my weight when we started going out together.

We had a pretty active sex life until recently too, even though she can get tired after a long day on her feet.

Recently, while she was out, I had a few mates round to watch a football match on TV.

I was messing around with one mate play-fighting for the last can of beer. We started wrestling and I began to get aroused.

It was very awkward and I have not been able to stop thinking about him since.

He is awesome – fit and good-looking. When I watch porn now I focus on the guys not the girls, and I no longer get an erection with my girlfriend.

Should I explore my curiosity with guys or at least talk about it openly
