Self-fuck Aneros/perineal muscles?

I honestly just discovered that self fucking was a thing let alone possible. I attempted it but it is very hard for me to get it in. I have no problem reaching its just unable to actually go inside. Maybe with more practice. I have no idea if aneros has affected this or not.

Yes I've done this, on rare occasions, for years now! It's more cool and interesting than stimulating. Although feeling your cock head swell while its inside your own ass is really fun and can feel quite good.

I don't think the strengthened perineal area is your issue. What always works best is being really, really warmed up before trying. So if I'm having a massive prostate/anal session, especially using dildos of any decent size (bigger than the aneros at least) and my sphincters are warmed up and loose I can get myself in there. I'm a bit on the bigger side too, but it's not an issue, actually once you're in and if you start to get a little hard your glans might act as a natural butt plug and stay in easier. Plenty of lube helps too. Depending on your curve, size of balls, etc., you can actually fuck yourself, like pushing your cock in and letting it come out on its own and then push it back in, and that can be fun.

The real mindfuck, though, is cumming in yourself. THAT is intense!! Your cock is cumming, but your orgasm comes from your prostate, which is at the base of your cock, so as your cumming your anal sphincters are pulsing and squeezing, and they squeeze your cock, so it's a feedback loop and it's very crazy!!! Sometimes I pull out and don't cum inside, because I'm still soft and the cum just shoots and pours out like wild, it's a most interesting form of orgasm and ejaculation. Try them all!

@JD05 the answers are yes and no. Yes, I can self-fuck which was the trip I was on before discovering Aneros. It took me a year to accomplish and now, it's easy and fun. When I do it, it's during my morning shower. My key to entry is to be soft and grow once inside. I ejaculated inside only once and it was intense but not enough to do so again.

No, a stronger PC muscle does not hinder the process.

I don't self-fuck much anymore as I'm trying to focus all my sexual drives towards the prostate at least until I get to my goal. I know I can do as I can edge and MMO doing it but these are things I can go back to once the goal is achieved. I'm trying to stay away from all penile activities and this includes SR.

Good luck and enjoy!
