Am I passive or am I just confused?

I'm 18 years old, I've never had a real sexual or romantic experience, but I use the internet a lot, and currently I'm more sexually and romantically attracted to men, however I don't feel any desire to have sex with one. Am I confused or am I just a passive partner? I feel sad about being in a relationship with someone because if the person wants me to do that, it simply won't happen naturally. Please clarify this for me based on your knowledge.
