Here is an email I sent out to someone wondering how to self fuck.

As a beginner, you must be soft when you twist your cock around - once you get more experience it's easier to twist it around while semi hard (but not hard of course!).. You'll have it in your head on how to feel and you'll get to know how to do it easier with every attempt. Read all of this before attempting so you get a feel of what I'm talking about first, please.. else if you try while reading you miss some info - I type as I think haha. Anyways, with your cock completely flaccid, lube up your ass and then only a very small portion of your cock head.. If you lube up your entire cock, you'll set yourself up for instant failure because your hands will be slipping all over and you won't get any friction to press on your shaft. If you get hard or semi hard during this process, end the process and then wait for your cock to go flaccid - search something on the internet, or something to take your mind off it. When you go back, twist your cock around so the helmet is facing the opposite way and then press it left and down towards your ass (so your cock is now towards or on your ass but on the left hand side.. your balls will be on your right) -- again, if you get hard during this process, it's best just to sit there and think of other things while you wait for the erection / hardness to fade.. If it doesn't, don't get frustrated, just try again in a bit..

As far as hand placement goes, you should have your left hand now holding your cock down towards your ass or against it (inbetween if you got that far).. Before you do this, I'd have A) 2 towels wrapped up tight for something to sit on, or use the side of a bathtub, but use towels laying on it before you try, else you're bound to hurt your hands..

When you're set, cup your right hand over your left hand that's holding your cock sit down and push your cock past your hole (past is the key here).. So you're sitting on the floor or bathtub with your left hand on your cock and your fingers so be under your cock head, and your right hand is there for support / helping.. When you're ready, slowly cup your left and right hand so your cock slides down your ass towards your hole, once it gets near or on the hole - start thinking of something else or something that will get your mind off of what you're doing.. If it goes in, congrats! but in 90% of the cases, it won't go in.. this is because you are not relaxed.. Think of something you did yesterday or what you're doing tomorrow.. or something you've read.. anything to take your mind off of it, all while still pressing and sitting on your cock. If you feel it start to go in, you can pretty much keep that pressure on it and try your hardest to relax and it might slowly slide in..

Chances of you cumming in your ass at first are slim, very very slim. PLUS remember that your cock is twisted, so the cum won't exactly "shoot out" as it would with regular wanking off.. Think of it as a bent hose. once you pull out if you do cum, it'll come oozing out. A rare few times I've been excited enough where I've managed to get *some* cum inside me.

Questions? Remember.. don't get frustrated.. If you get sore or start to hurt.. stop and try again later. Don't hurt yourself doing this.. if your cock gets hard, don't force nothing, just let it subside for awhile till it's soft again.
