Reciprosexual

Reciprosexual or recipsexual is a sexual orientation on the asexual spectrum meaning someone who does not experience sexual attraction unless they know that the other person is sexually attracted to them first.

Reciprosexual can be a sexual orientation on its own or can be combined with other orientations. For example, one could be reciprosexual and gay, meaning that when one does experience sexual attraction it's only towards people of the same gender.

The romantic counterpart of reciprosexual is reciproromantic.
