a slayer ? I think you mean a person that easily gets women, but I don't find that meaning in a dictionary. a slayer = a killer; a murderer; a destroyer of life
My answer: if that is someone's situation here, he has hope. My mother has all my life (I'm 30, I've lived alone since being 19, I don't speak to my parents often) pretended that I am not a sexual being. She knows that I have no chance whatsoever. When I've for example recently complained to her about yet another big under-the-skin pimple in my face, she goes uneasy, awkward, embarrassed. Like that it makes no difference for you (me!) because even without that you would be so ugly-looking that additional ugliness does not matter and you don't have the right to try to look a bit less ugly.
My father (my parents separated when I was still living with them) is different. He does not pretend that I'm not sexual. He knows (I've not told him that I'm still a virgin etc.) my situation and sympathizes. He himself had big problems finding a girlfriend and marrying.
