Ideas for Male Selfbondage Orgasm Techniques

I’ve been practicing selfbondage for a while now, and using just a buttplug isn’t enough to make me cum. I’ve tried the puppyplay tie, the hogtie, and many other positions with both a buttplug and dildo, but I only reach orgasm when I intentionally get myself into a spot where it seems like I “can’t” escape or have to struggle in an awkward or painful way to play with myself… So here’s what I’ve got: a blindfold, an inflatable vibrating buttplug, a standard medium buttplug, a strapon, a pocket pussy, a suction cup dildo (roughly 7.5 inches long), and a Hitachi wall-outlet vibrator (though it can be tricky to incorporate into male selfbondage setups).

Do you have any suggestions for positions or arrangements that help me cum without overexerting myself? I haven’t experimented much with homemade cock ring devices yet (visuals would be helpful). I’ve also attempted sucking my own dick by lying down and lifting my legs up and back, but I’m not quite flexible enough anymore—I did manage it once a few months ago. If anyone knows of a better technique for self-sucking that works well too.

I considered tying the pocket pussy directly to my penis, though I worry about stability. It would be great to replicate the sensation of being penetrated by a dildo or similar object while using my own shaft (kind of like having the pocket pussy mounted on it). Any thoughts?

Also, with the puppy play setup there isn’t an ideal spot in my house for positioning the suction cup dildo properly for good penetration; it’s slightly difficult to thrust effectively that way. Other positions work okay too, but they aren’t true self bondage since I have to manually stroke myself.

Any ideas at all are welcome.
