Hi LH! So the book about multiorgasmic man has all these breathing and muscular exercises to gain better control over ejaculation and so on. Then you have a lot of content on healthy masturbation and understanding your body in a better way. When I am in between physical exercise or have some calm time or in bed, I repeat these exercises. I have not been able to test if they work as I am not seeing anyone so my sex life is non existent but I can say there have been good results when alone! hahaha
I think dudes just need to get out of their own heads in regards to sex. Thinking/worrying about your performance should be avoided. Positive thoughts. And avoid too much masturbation. That can numb your member and affect performance.
I agree with Harvey. Just don’t be selfish and make sure momma gets hers and the rest will work itself out.
