I am a girl . I like girls way more than guys

I am demisexual and the fact that guys approach me because they want a date or a relationship or just sex really really turns me off

For me to get into relationship I have to start with plain friendship first, I have to have a bond with them and know them as person to want a relationship .and the fact guys approach me with unpure intentions, really turns me off . Like I want friendship developed to a relationship, not start with a relationship

But I always get confessed by every guy I met but I am not attracted to any of them

I will meet a guy , wanting friendship so when they approach me I always talk to them and hang out with them because While every time I am attracted to any girls they either taken , interested in someone else , or simply just find me annoying

I think the reason because I approach them , wanting to be friends . Start as friends first and to see if I like them . But after I have a bond and feel close to them and I like them , but they never like me back

Anyone else have the same problem ?
