I do sex every dy but one time only I want do more but after doing ine time my mood was changed?

I assume you are masturbating every day and not actually having sex with someone?
Either way, It is not unusual to have mood changes after sex. We all get sexually 'pent up'
and having an orgasm releases that 'pent up feeling, so it's not unusual for your mood to change. Some men get very 'high' after orgasms and others get very down a moody. I guess it depends on your personality. Don't worry about it!
