I've been doing this for about two years now and to be honest a wouldn't really say am addicted, I feel that I am in pretty good control of my punting urges and there have been numerous occasions were I've cancelled punts purely cause I just couldn't be arsed (the prossie always got plenty of notice before anyone acuses me of time wasting).
I get plenty of sex out on civvy Street from girls that I meet in bars, the gym, there's a girl that I've known for about a year and a half now and we have a pretty good 'fuck buddy' relationship on the go, so for me it's never a case of 'I need to go on this punt cause it's the only way I can get my hole', I punt purely for the convenience, because I get the opportunity to try out different things (TS, duo, role-playing) and also because every now and then you meet a prossie who is just a great fucking shag and you want to see her again, Maisie for example, a number of TS's that I've seen more than once etc, etc.
I'll probably stop at somepoint and if I was to ever enter into a relationship, I would stop straight away without any hesitation. But in the meantime, I'm young hung and full of cum and have no intentions of stopping just yet
