I've done a lot of research on ways to achieve multiple orgasms...which i mostly planned on using as a way to make up for my problem with premature ejaculation. So I did the PC exercises and I'm fully able to hold back my ejaculation by clenching it when i orgasm. Every source on the topic that I have read has said that it is the actual ejaculation that triggers your refractory period, so if you avoid ejaculating, you avoid going soft and keep your hard on. Well this isnt the case for me. After trying it several times, I hold back my ejaculation but still lose my erection right after. I can eventually work my way back up to another hard on but it takes time, and I lose all desire to do so. And I've only given this a try by myself, not with my girlfriend (although once with her I managed a multiple without even trying while getting a bj/hj) Has this happened to anyone else who practices multiple orgasms? The point of doing this for me is so I can keep going after my first orgasm without losing my erection, so avoiding the refractory is my main concern. Is it something that just comes with time and practice? Am I timing my PC clench wrong? If anyone with experience could offer some insight I'd appreciate it.
