You will need to explain this more because I have not heard it that taking alcohol can help a man sexual performance. Rather what I have heard is that alcohol is likely not to help a man in sexual performance. I believe that we should do things in moderation because whatever we do excessively is an abuse and likely to demage our system. Those who are addicted to alcohol have not confirmed that help sexual performance rather I think what affects sexual performance is mostly age. You don't expect an older person man or woman to as active as a younger person.
