(Adj.) Someone who's sexual and/or romantic attraction is solely based and/or allowed by the chemistry shared with another regardless of gender or even lifeform.

It is most noticeable in bisexuals as they will prefer relations with one gender over another based on the chemistry shared.

Often confused with asexuality when the individual stops having chemistry with others.

The opposite of this would be someone who only has a romantic or sexual relationship only driven by physical attraction with no emotional side on the matter or chemistry.
My chemosexuality wont let me have random sex.

I have been with girls but I'm such a chemosexual for guys, It just flows natural.

I don't care how hot he is I don't like him, maybe im being a chemo about it.

You're such a chemo!
