I can reach orgasm.. but because of the twisted nature of the shaft not very much comes out and into your anus. It just kinda dribbles out of your shaft once you pull out. In the years I've been doing it, I think I've only blasted a whole load into me maybe 2 or 3 times. Warming up your anus can help, but you cant go too long or your sphincter will actually swell a bit making penetration harder.
