It's only getting better - the urges to touch penis faded away so that now I think about this part of my body exactly like this - just a part of body which I wrongly associated with true sexual satisfaction. Interestingly, the thought itself is a turn on.
During these four days I think I had about ten anal orgasms and one nipple orgasm. I can only repeat what I was saying previously - it feels so much natural. I'm going to write an update to the blog soon with guidance as to how a male can achieve an anal orgasm - I believe that most men are capable of it. I think that the most important component here is psychological - it really turns me on to imagine myself as a girl and feel so sensual. If this is a fetish then I actually do have one.
For years I was ashamed of this part of me but now I have every reason to believe this is natural. I'm not transsexual, I'm perfectly fine with my gender and I have all the (stereotypical) traits of a (manly) man. It's just that when it comes to sex the psychological pleasure of feeling sensual, of being so sensitive for a moment is much more satisfying. I even checked the research on cross-dressing and it turns out it is much more popular than one might suspect. Additionally, over 90% of cross-dressers are straight males fine with their gender.
So, the advice I could give you is to focus on psychological pleasure and let it all go. Possibly imagine yourself as a girl which is about to have a squirt - I'm serious about it, it almost always pushes me over the edge.
I think all the ideas about semen retention are little more than bro-science. Semen is produced constantly and it is not that much "costly" for an organism to produce it. I think that benefits of NoFap come from ceasing of triggering some specific neurological pathways activation of which lead to some pretty bad side effects in some people (or even all males when activated excessively). But again, this is just my theory.
I ordered a G-Spot vibrator which I'm going to use to focus on my prostate. There are anal orgasms which feel like taking a dump in a very satisfying way and there are also prostate orgasms. The first kind can be achieved by focusing on rectum, while the second (even better in my opinion) possibly can make a guy squirt - not semen, but some other kind of fluid (not piss as well). I have read some reports of that and I think I was pretty close to squirting last night. Also, male squirting can be achieved by stimulating head of the penis in a specific way (search for "male squirting compilation") but all I achieved was normal (albeit stronger) ejaculation and, unfortunately, this way of penile stimulation has all the downsides of good ol' fapping.
Hope that helps! I'm going to share more observations on the blog over time. Not sure if I will post any photos - I'm not comfortable with that and pics of my pleasure zones wouldn't help much anyone in achieving anal orgasms
There is no point in using the penis, it's only a habit and a temptation to get rid of. More in my update on tumblr.
