I thought i was going to be the first "deviant" to come out of the woodwork but someone has beaten me to it lol (no puns intended)
Mephedrone has taken the edge off wanking for me. It used to enduce sheer desire in me and make the whole process of searching for and finding images or clips that would make you go "cwoargh" or "wow beautiful" very exciting and immersive, Well nearly every image would have this effect on Mephedrone. Spending hours spinning things out and building up a new collection until finally deciding thats enough lets go for it now...
Now without Mephedrone wanking is nowhere near as fun or exciting....PV isnt the same for me in this regard....although it does have some effects on desire at certain points of the ride
Cant even be bothered to try any more most days anymore, guess this might be a natural turn of events for someone at my age (post 40) just that Mephedrone made these things happen rather suddenly.....
