No to put a dampner ear on your idea, I was with dirty Daniella recently who used to work in porn. She has done dp and said to be honest, especially for the guys, it's all very awkward with 1 unlucky sod mainly just lying there. She said it's no comparison to how you see it done by elite porn stars.Good luck tho.
I'm just wondering how safe rubber on rubber is? I assume you are not talking BB here
