Sexual orientation is not the same as liking penises/vaginas or bodies. Sexual orientation is in the mind and the way someone with X gender makes you feel.

If you believe attraction and love is purely sight-based, I think you may not have found the one yet. If you don't believe this is the case, this question shouldn't need answering.

Like ...I'm legit not trying to be snarky. Either you believe attraction can only happen when one can see the other, in which case I can't help you, or you don't, in which case you don't need help to begin with :)

You know who you fancy and if you're turned on without seeing someone, yes the visuals are important for someone who sees but it's not the only thing.

How do you live without hearing or a sense of touch or smell?
