Prostate play before getting fucked

I’ve had a couple prostate orgasms without touching the front, although they were all wet, but rarely. I’ve had good feelings you could describe as orgasm-like but never as explosive as a full wet prostate-assisted orgasm. I’ve never had an full satisfying orgasm from just being fucked by my partner unfortunately.

I normally use shorty before an Aneros plug, both because it feels good during foreplay but also to have the first stretch going to make everything easier later.

Now I wonder. Normally in the case of penetrating sex, when you would jerk off before without cumming you are putting yourself to orgasm quicker. You are gonna last shorter basically.

Does this also apply to prostate play? Does it bring you closer to an orgasm before having sex? Does it activate your prostate basically. Or does it take pleasure away from the real experience later because you ‘used’ it partially? And essentially numb down the pleasure later?
Because I’ve had moments during solo play I reached great heights, never got to the finish, and after a quick break of getting water, never got to the same point anymore.

Does anyone have any clues on how this works?
