Can I Be Straight But Asexual At The Same TIME LIKE For Example LIKE Girls But Not Want To Date Them Or Have THE Desire To Marry?

Asexual doesn't mean you don't wanna date/marry them, it means you don't want to have sex with them. This question doesn't sound like it makes any sense.

Sounds like you could be hetero-lithromantic. You feel romantic attraction to the opposite gender but you don't want a relationship.

No reason you have to label yourself at all, or allow others to label you. Lots of guys don't date or have relationships with girls. Normal.

Asexual means you are not sexually attracted to anyone.

Most people like (at least some) other people irrespective of whether those other people are men or women. Think about the cliche of straight women liking gay men - while its a stereotype it does hold true more often than not! The reason being that gay man are usually (not always) less threatening (not being after sex with them) compared to straight men.

If you have zero, or very low sexual desire (all around) then you are asexual. Trying to also class yourself as heterosexual is a nonsense, and you may want to try and figure out why this is important to you. Our societies are not good at dealing with (any) alternate sexualities and you may find that a visit to a sex therapist would be useful, just to get your own thought together!

Don't see why not.
