You're quite on point about it being an addiction. Sex is, and can be a real addiction. Similar to alcohol, porn, drugs, etc. The key difference is that sex naturally occurs in our lives, which makes an addiction more difficult to treat, as you can't generally quit it for life. If I recall you just recently returned to hobbying. As did I, now from my recollection, (it's been almost six-seven years) I didn't see sps/mps as often as I am now. I'm seeing them once or twice a week. Which is fucked, from a monetary perspective most especially.
So I'm with you, I'm not sure if this is just a phase as I'm just returning to the hobby. Or if I'm fucked and right addicted lol.
If you want to piss yourself off, think of the opportunity cost of your hobbying. If you spend 250/session, and have 4 sessions a month. You've spent 1k. Would you rather have had a new 50" TV on your wall for that 1k? Or a new suit, or watch, maybe a trip to cuba. Those items are your opportunity costs.
You may be better off setting out a budget, how much you are willing to spend on hobbying. Now if you've got a large amount of disposable income.. well. This makes for many women, and leaves you back at square one lol. To poon or not to poon.
I personally hope it's a fucking phase.
