The problem I found is that it comes in cycles...you go a few years crazy, then you wana calm down then you wana go crazy again...
I went crazy in late teens, early 20's calmed down and got into a relationship (5yrs) then broke up stayed calm, then I hit 27 and went ape shit, parties all over Europe every weekend, girls coming and going I hardly had time to sleep, now last two years I calmed down but I know not to settle down incase "crazy" comes back...men do have another round in them usually when they hit 40.
Maybe, probably partially genetic. I am severly understating how bad I was in my 20's... Not in a good way. It devolved quickly into drug addiction and all the shit that comes with it. Its fun for a bit, drug sluts are fun, but it gets old fast.
And it's lonely. I've had enough of that for a lifetime. I still get the itch now and then, but having a nice, stable life with a loving family is far more important to me than anything else. I like waking up to someone that I don't have to worry about impressing, that I'm still attracted to everyday, that makes me grow and challenges me and that also takes my challenges and grows.
Some people can't/don't ever find a parter that complements them and that they grow together and push each other. Most people slowly grow apart. Ours has been exactly the opposite, and it's probably because I was extremely picky with who I would be with. After all the headcase/fucked up/daddy issue sluts, both drug users and not, I knew a good one when I saw it. Plus she was young enough not to have been fucked over and jaded by shitty guys.
Its not for everyone, by a long shot... but the hardships I've been through, both by myself and early in our marriage, has done nothing but bring us closer together.
