Sexuality Probelms

So I've been thinking about it for a while now and I just can't figure out my sexuality. I would date anybody regardless of sexuality or gender (so I thought I was pansexual) but i could never see myself having sex with anything other than a guy. But even then, I don't like the thought of sex but I still watch porn and fantasize about sex. I'm so confused, some people call me pansexual and others call me asexual. What the hell am I? And I'm a virgin and I don't just want to give it away "experimenting". Please comment any advice that you think would help
