When I was 18, sure. To answer your question seriously, first off all I am not looking, but if I were, I am afraid the answer is No, I would not sleep with an 18 year old girl. It would feel too creepy.
Not to mention I would royally fuck up a young girl’s view of what sex is supposed to look like. Unless you only dated older men, I imagine I would do you a disservice by having super-aggressive orgasm-overload sex, because the next guy you sleep with will probably be 18-21 and won’t measure up by comparison, and you will say something is missing with him, when in reality, he may be the perfect guy for you, he just doesn’t know how to make you cum yet. Sometimes I think the young demo that follows this blog should take into consideration that they are just not mentally ready for D/s sex. Or if they are, their partners aren’t, and they may just need to grow and learn like the rest of us had to.
Self-discovery is a beautiful thing. Just see it for what it is. Any 40 year old man willing to fuck an 18 year old girl has some deeper issues in my opinion, so you should keep that in mind.
But that all being said, I am still a firm believer that Love conquers all; if Love is involved, then all bets are off.
Thanks for the Ask,
