There are lots of tips on male sexual health out there from magazines like Cosmo, Men's Health, and so on - but here are just a few that will help you in general from my own experience.

Male Sexual Health - Two Tips for You
  • One thing you can always do for good health and vigor is workout consistently. Not only will this make you look more attractive to the opposite sex, you will raise your metabolism and sex drive, as well as testosterone. You will, in essence, become more of a man than you are when you aren't active. 
  • Learn to focus and be confident. Confidence is a learned behavior - so is focus. Often times a premature ejaculation or poor performance in the sack is really just like not having studied for a test. The more easily you can focus in real life, the more easily that skill will help you in bed. Being a good lover is not about how big you are, it's about how focused you are on pleasing your partner, and that is true male sexual health in the mental sense.
