Welcome to our forum.
Do you have quite a depth of emotional closeness with people? Perhaps the emotional component is what's missing; it's not strong or deep enough.
Are you happy with the way things are, or would you rather have more intimacy with other people? Part of your objective here should be determining what you want.
Do you feel you're mostly asexual, or just that something is holding your sexual and romantic feelings back? When you go on a date, how does it usually go?
I think you're just figuring things out right now. You'll get them figured out.
Love means never having to say, "Put down that meat cleaver!"
