Will prone masturbation make it difficult for me to have real life sex?

No not at all.: Masturbation is normal for both men and women as they enter their sexual peaks. 50%of all young men masturbate, the other 50% lie. So not to worry there are no adverse effects to self gratification.

Prone masturbation: This is sometimes reported. Frequent male prone masturbation place significant pres-sure on penis & nerves at its base. There may be numbing to arousal / pleasure. Seek help for delayed orgasms, erectile dysfunction or inability to achieve orgasm in other ways. It may lead to back pain in males & females.
