You could kiss or make out with the same sex but that's all about it. You could never go out with them because you don't feel enough emotions for them or do anything about them such as sexual intercourse.
Wallsexual came from the word "Wall" which means to subdivide and "sexual" means occurring between or involving the sexes
"Wallsexual": It's really hard to make an example about it. It's basically just the definition and it just what it means.
