One of the most asked questions among men is how to maintain an erection for longer periods of time so they have have sex for longer. For most men they can only keep an erection for not more than 3 minutes after intercourse begins. This is just not going to work for most men and it does not allow enough time to arouse women so they can have an orgasm. It takes at least 10 minutes of intercourse to sexually arouse a women to get her to climax. So men need to maintain an erection for a longer time.
