Well heya there Luke! First off I’d be lying if I said I haven’t been dealing with the same issue recently.
First off I should say that being Bi doesn’t necessarily mean equal attraction to genders, and there’s no quota to say that you have to have to have liked/dated a certain amount equally!
As for opening up on liking men more, that’s a little more to do with personal comfort, and if I’m saying from a personal level I just started liking fictional guys and discussed them with some friends, and we sort of made a comfortable space and it got to the point where I could really start to admire guys fully. If you do ever need someone to be that person, drop your URL in our ask box and i can PM you.
