Tactusexual

Tactusexual is a sexual orientation on the asexual spectrum describing someone who can only develop sexual attraction to another person for the time they are having physical contact. Physical contact, e.g. holding hands, cuddling, kissing etc., is necessary to open up possibilities of sexual attraction. The development of that attraction starts with the physical contact and disappears a short amount of time after the physical contact ends.

Tactusexual can be a sexual orientation on its own or might as well be combined with other sexual orientations to specify the gender or other information.

Etymology
