I m naturally flexibile and have low body fat. I can suck half of my cock with no problem , but only in plow position.
What's really upseting me is that I achieve all. ( streching , empty stomach, im horny and all )
But very soon my dink becomes soft , even than i Can suck entire head, but it's a A LOT less pleasurable and I im unable to cum.
I just need something to give me rock hard erection in plow position ( google it you don't know )
The main problem is blood flow and semi erection or soft erection. Need help asap.

P.S. Cock ring is out of option. I once hurt myself with it.
