How can I act more like a guy??

Some people I know think that I'm either gay or bi..I'm not even sure what i am..But i want to fit in better. I hang out with girls and guys...I'm perverted sometimes..But sometimes I'm sure i say things that make people think....My voice is not high but not low either...I sometimes listen to girly music like Rihanna, Justin Timberlake..And people think its wierd that I go to girly concerts(Justin Timberlake, Gwen Stefani) Or when I got all excited when I ran into the Jonas Brothers in NYC. Please help me! I want to be more of a guy. Serious answers please.
