You love a person, not their gender segregation, and this love will more than likely develop into a sexual love.
It's like saying you don't like all chocolate because you're not keen on Turkish delight, you know? This is called asexuality, but some asexual people are still interested in developing romantic relationships with other.
There's nothing wrong, invalid, or broken about you or how you feel. You can experience romantic attraction but not sexual attraction, or the other way around, or both or neither.
You can also experience romantic attraction to a different group of people than you experience sexual attraction. Sexual orientation is different than romantic orientation.
But there's nothing wrong with that, some people are attracted to someone only sexually and not feelings and other wise, but it's all due to that person.
Yes, and these feelings may change as you develop relationships with individuals within that gender.
There's sexual and romantic love, and we can feel them exclusively for no gender, one, or multiple. Liking women but wanting to get into a guy's pants. Sexual is when you feel attracted to someone in a sexual way, and romantic when you feel attracted in a romantic way, and while these two types of attraction come together a lot of the time, some times they don't.
Aesthetic attraction is when you're attracted to someone's looks but not necessarily in a sexual way, and sensual attraction has to do with the senses (wanting to touch, smell, see, etc a person)... Romantic attraction often correlates with sexual attraction, but not always.
Of course, there's nothing wrong with not being sexually attracted to someone but still wanting to be with them.
I mean, they might not be okay with that and think it's not worth it, or they might be with you.
