I'm with someone and I know he doesn't mess around. He is in his fifties and I am in my twenties. I like older men, but feel like I want more experience. This would upset him if he knew I felt this way. He is a very nice guy and I love him a lot. But sometimes I want to be with other guys. I have only jerked off with a few, one time only deals, no kissing, not much cock touching, mainly jerked off. Tonight I did with a guy who had a big thick cock...it was fun, but I don't know if I should feel guilty about it...... any advice?
