Now that princessa mentions it plentyoffish.com LOL Adultfriendfinder.com is raunchy but hey, it you are straight-up talking hit it and forget it - 3 somes, trannies whatever... I say go for it. You missed out on adult relationships and even know WHO YOU ARE by being in that longterm committed relationship when you were so young. So now I totally understand your "adolescent" take on dating. I was the same way. But since you are a grown man, trust me - you will figure it out quick. And once you get tired of just bangin the flavor of the minute you will become more grounded and know better what qualities to look for (for YOU) in a longterm companion.
THIS STUFF SHOULD BE FUN!
What I should do is gift you a copy of my book gratis... LOL
