Hi, I have had always problem in maintaining an errction while having sex. I have to do a lot of hardwork to keep my penis errect and because of that, i ejaculate early. my penis is always less than 90 degree when errect. is it usual?
I never read anything about a erection having to be a certain degree, 90 or otherwise.
Have you tried changing your diet? What you eat effects your penis. So you smoke? have you tried supplements like Endurnz or Enzyte?
Do you take your vitamins? B6 is very good. herbs such as maca and tongkat are very powerful.
