So I pretty much always suffer from premature ejaculation. What is the best way for me to go about having sex - especially with new partners? What should I maybe do more of, instead of penetration? How can I make sure that, even if it's short, my partner will enjoy the experience? Also, I last longer on the bottom - is it better to last longer on bottom, or shorter on top? Any additional information would be greatly appreciated, this situation is a huge pain.
