It does happen, that your ruins feel really good. It might just be that’s how you’re wired but what I’ve found breaks through (are we seriously talking about how to ruin an orgasm if we can’t, that’s so funny) it occasionally is ruin it from penetration, get yourself to the edge fucking a dildo and use that to take you over and pull it out as soon as you do.
Use clit stimulation to get you there, sure, but try to see if you can just go over that final edge with the fucking alone.
Also, if you can’t cum from just fucking, this is an evil task to have to do, forever teetering on the edge unable to go over.
Hmm, I think we might add that to the Orgasm Denial Lexicon
Teetering – to hold an extended edge
