I recently lost my virginity and had the most amazing experience doing so. However after maybe 15 times or so of having sex with my partner, I began to lose resistance and slowly I've lost all power to control myself like I used to (fresh off virginity I did much better than now!)

I've practiced masturbating and holding off orgasm but I find it hard to masturbate for a long time, as eventually, I have to stop every time I reach pregasm. The stops are more and more frequent, and I know that this kind of orgasm control won't be enjoyable for my partner. I've managed to have mind over matter before but sometimes it's just physically too pleasurable to control with my mind!

Any suggestions would be greatly appreciated.
 

The stop-start method, where you stop at pregasm, is an essential techinque when first learning orgasm control. Once you can recognize pregasm, then you can avoid tipping over the edge of orgasm, which gives you more time to practice sex for longer.

The next most important technique is PC muscle relaxation. This technique will help you stay away from orgasm but keep having sex without stopping. Practice this first on your own, then try it during sex
