You kind of have that teddybear face, big and not particularly refined facially, but soft enough and with those dark eyes you look like you could be empathetic and supportive enough to attract certain types of people that want that. Not sure if your rl personality fits that, though (like others are saying, likely not).
EDIT: For example, do you use the word "babe" a lot in a non-demeaning way? As in "You're everything to me, babe, let me sing a soulful little number for you", not "Damn babe you fine, wanna get down and dirty to some of my fine-ass experimental electronic music?"
EDIT #2: Like srsly, if you don't give off creepy vibes irl I'd trust you to hold me tight without feeling like you have other intentions (even though you do).
