Well, i've been trying my best with Karezza. The way i'm doing this is to give my girlfriend all the orgasms she desires. But i don't have any orgasms or ejaculations at all. I think that if i experience even greater pleasure while having sex without orgasm, then i could persuade my girlfriend to forgo orgasms too. But at the moment i am fine with how it is going - when she orgasms, her face is so adorable!
Both Tantric sex and Karezza teach us how to have sex without orgasm. But it is feeling impossible to me! When i went for a few weeks of no orgasm, my penis was as hard as a rock and very sensitive. When i inserted it in her vagina, i feel like i could ejaculate and orgasm within those few seconds! So i had to go much slower (which Karezza says is a good idea).
I spent more time looking into my girlfriend's eyes and kissing her everywhere. After a few minutes of going really slowly, i simply couldn't hold it in anymore and i had to ejaculate. It wasn't so enjoyable for me because i had to keep my muscles really tense the whole time. If i relaxed just one moment, i would ejaculate right then. It wasn't so good for her, because i was all tense and concentrating on not ejaculating. So i couldn't give her orgasms.
How do you do it? I know Karezza sex is meant to be relaxed, and arousal is meant to be quite low. I tried breathing deeply, but as soon as i went inside her, my penis seemed to have its own mind and wanted to ejaculate. And i don't know how to control it :(
Lastly, how do you stop? Since you can't have orgasm to finish sex, i assumed you just keep on going until the action of holding in the semen becomes so unbearable, you'll have to pull out before you burst something? That's what i did, but that's probably wrong.
P.s. A thread posted a few months before this talks about using the 'three finger method'. I tried that, but i'm not sure if that's a healthy thing to do to keep putting strain on that area. It works the first few times you want to orgasm, but it afterwards becomes harder. I'm very unsure about this whole thing. I don't want to get problems in that area as an old man from all that pressing, pushing and holding!
