Am I wrong / cruel / or right ?

please give me your opinion…

for the last year and half i have been single…..i've had the odd date, a few guys have expressed an interest etc and i have expressed an interest in a few too.. however there is always a problem i've had since I was young….

whenever i like a man sexually, they don't like me the same way, or they do but as people they are horrible people….So all these guys who have expressed an interest in my lately have been lovely people but i just don't fancy them..(i think this is very important in a relationship, especially for me, i HAVE to find them good looking)

I know everyone will say its what's inside that count's etc and Beauty is only skin deep, and that personality counts for more…BUT could YOU kiss someone who you didn't find attractive??? I CANT….

so my latest dilemma is thus…a recently met a guy, we get on well enough, he is kind, considerate, helpful, sweet, everything you would look for in a man….i think he wants to be more than Friends too..However he is REALLY unattractive and the main problem is that he has the worst teeth i have EVER seen….they are practically green…i know if he ever went to kiss me i would feel sick kissing him, and could never see myself feeling sexy or turned on when he touched me. I actually am gutted i don't fancy him. But i don't know what to do…
