Let me try to straighten this out out loud: (1) We develop sexual desire because we evolved to do so. Indeed without it we couldn't have evolved. (2) Sex is essential for starting a family which is extremely beneficial for your physical and mental well-being. (3) But too much masturbation/sex is bad for your physical and mental well-being. (4) In particular sex can be an addiction which changes the way you view reality (up to and including preventing you from acknowledging this. People used to call this sin. Actually I think some of them still do). (5) Yet telling people that sex/masturbation is sinful can be repressive and harmful. (6) Unprotected sex leads easily to STDs (which in the middle ages were no doubt widely considered to be divine punishment). (7) Education is a vital means of preventing STDs. (8) Yet talking about sex is generally consisdered rude. (9) As is having sex in public. (10) Yet sex addicts and religious maniacs think about sex all the time... It seems the topic remains confusing half a millenium after the middle ages. Please don't take this as any kind of advice or political statement.
