My reasons...
I dunno I am quitting honest to god.
Iceg... bro to bro... sounds like you have had some rough luck with woman there... feel for you. Know the situation.
My story...
I went 4x a week in october-> january... then down to 1x per week->1 every 2 weeks->then down to 1x/3weeks->1time/4 weeks. It was my plan to quit this way and it is working i believe. I have tried cold-cut quiting. That doesn't really work.
Being a younger guy (21) i think that pooning is good to fulfill sexual needs, but other than it can cause some problems at least for me. It became addictive, and left me feeling lonely and craving more. I think the more and more you go to sps, it becomes kinda routine, something you do. Very addictive.
I think if you find a good woman, you get much more satisfaction and can save some money (at least the way I spend money on sps.... lol.... not kidding here guys I think in my prime i was spending like 1000+ dollars a week on 1 sp

you know the two sps i saw

) That is why i thought it was time to quit. Sps are nice, for the sex.... but I think it left me with a bit of an emotional void. That is a part that i miss in a real relationship.
If sex is really important to you, an sp should be your thing... otherwise i dunno you gotta look at yourself individually. Me personally...I am still young, got a bit going for me, know i could treat a lady exceptionally well. So it was time to quit. Findng the right person is hard, but it is a search even for a great sp. I think part of my problem is being quiet and isolated in the real world. I am not really anti-social. I just stick to my same group of friends and family, and it is diffiicult to meet new people that could suit me that way + having a bit of money at a young age and being stupid with it led me to seeing sps.
