How to be more exited in a sex relation ?

Talk to your partner: It's not clear to me what you mean by "more exited". Are you asking to increase your sex drive or libido? Or to deal w/erectile dysfunction? Or some other issue? All are addressed differently to some extent. But at the same time, good nutrition, regular exercise & healthy lifestyle are imperative. In other words, don't smoke and don't drink to excess. Plus don't do drugs. Write back w/specific qs.
