So i've come to terms with my dick not being huge. just over 5 inches fully hard.

I've fucked girls in the past and they seem to enjoy it. But it's always been skinny girls. I'm having a not fat, but not thin hb7 coming over next weekend to fuck. She has meaty thighs. My question isn't so much one about mindset or whatever, but the physics of the situation.

I'm worried I won't be able to ram her from behind or do any fancy positions. Surely she will get bored if I can only do her with her legs in the air?

Any other less well endowed lads got any advice on how they keep women coming back for more, greatly appreciated.
