We're waiting for you to explain or elaborate upon your situation, M'sieur mikespike. Are your brother Espiyas correct in assuming that you've been overindulging yourself when it comes to masturbation and watching pornography?
In the meantime, you might try the suggestions put forward by Seigneurs gh0st, SpyTamers, and Jann Frost and try to substitute some other activity for your two current "pastimes". It would be preferable if the substitutes you choose have nothing to do at all with sex.
