Dear Dr. Betty,
I am 16 years old, and recently stumbled upon a video of yours, having to do with penis size. I recently blew a chance with an older, experienced girl, and just recently started "hooking up" with another. I feel as if my dick will be a joke to experienced girls.
I'm a late bloomer, and am expected to continue growing in all areas of my body, however, the girl I am with at this moment is down to have sex. I've already done oral play on her breasts, and I know for a fact she wants to fuck. I am worried she will just laugh about my dick. its not tiny, I'm around average size.
You fear is common and it's unnecessary. Girls rarely laugh at dicks unless they are in a group and being nasty. It's mostly guys that make fun of each other or make comments about girls tits and ass.
So in order to get over your fear, bare your penis. Take him out for a test drive. First time sex will most likely be over in seconds so rest a bit and go again. Enjoy.
