Helping With Problems

My big bro who knows my love for 2d boiss who wears specs and glasses asked me if it's my kink (we're both degenerates, he has a twin tail kink) and I said Idk since I don't pay attention to men irl wearing glasses and like here in my neighborhood there are only like 4-5 men that wear specs. So my brother tries to call his bestfriend (also my suitor) to try wear specs and see if my glasses loving ass is applicable irl BUT I HATE IT, IT WAS HORRIFIC. Since Thursday my suitor's been wearing glasses and how can I say to him that I don't have the glasses kink irl but only in my anime boiss and to say I don't really like him without him guilt tripping me for not accepting him (he's been courting me for months and everytime I try to reject him he's been more persistent, he's a creep tbh)
