How did you decide which donor site to use and how long did it take you to make that decision?

I've known that I want phallo for years, but keep swinging between wanting RFF and wanting abdominal phallo. I prefer the scarring of abdo, but I want the best chance of sensation, as with RFF.

I also don't want to feel bad about my arm or for women to find me less attractive - I don't know how they'd feel about my arm scar.

How did you decide which to do? How can I decide?

Thank you
