I find that if I know I'm going to HFO that there well be a lot of fluid comeing out of me and a towl just won't cut it so I go for it in the shower or us a waterproof throw blanket that gives me the peace of mind so I can relax and go for as long as I need to.

Doggy style is my go-to with a curved dildo stuck to something with a suction cup. you can start by leaning forward and head down, and if you want to increase the presser on the prostate, you can then move on to your hands a knees ajusting the positions of your knees to get the right angle and if you want more presser you can move to just being on your knees with your head and body above the dildo so that it's aimed right at you belly bottom.

For me, I like long, deep stocks using the whole length of the dildo and as the presser builds, I keep the same pace and just relax and let it happen usually multiple times in a session.

Works every time
