Most erotic memories I have.
PoshPorn Sindy with a mouthful of cum dribbling down her tits and her chin, looking at me and saying, 'Your sperm tastes really sweet today', then snowballing me.
Girlfriend Jenny with a string of my cum hanging off her bottom lip, smiling at me.
When I'm older and greyer, those memories will stay with me forever.
But to answer the OP's question.....probably, in the heat of the moment. Definitely, with the right girl with the right body.
