The only thing that makes you from the photo is the eyebrows. I like girls, and slender ones at that, but I have straight male friends who look pretty similar to you and with the right confidence have done quite well with the right lady. You have the teddy bear look, which makes you seem safe, so if you're after a long-term relationship you'll do fine--you just need to make sure to look for women who want a nice guy and have gotten past the bad boys.
Here's hoping your long-term friend hasn't put you in the friend box yet! If she has, take if from me: Step back before you get too interested. The years wasted on uninterested women friends, I could tell you stories . . . Good luck!
