Seeing naked men is kinda erotic in the right setting.
We enjoy mfm pretty regularly with a guy we know.
It's not him that's sexy...it's the whole dynamic. All of us naked together, seeing him move with her, her move with him, them moving together.
He does look good standing naked and hard. VERY erotic, sexy, hot and exciting to see him pull out after, sperm drip off his wet dick. See her on top and him cum, it oozes out down onto his balls....yea it's fun but I have no desire to play with his dick.
