Before recently, I really only worried about the girl's pleasure during sex. Probably because I used to have PE and was self conscious about it (still not sure why that went away, more confidence maybe?). Even when I acted like I was just ravishing her solely for my pleasure, it was mainly because I thought she would like it like that. But over the last few months I have gotten quite good at sex and am starting look towards improving sex for me. Are there any ways to make the male orgasm more intense?
So far all I really have is trying to hold it in as long as I can during my "vinegar strokes." Also I know of prostate massages, but I'm not quite ready for a finger in my butt. Also, I'm interested in tantric sex, but I usually take a while to get even close to where I would cum (If I get there at all), and am often exhausted or it's getting too late.
So any ideas (or material) about how to make your orgasm more intense?
