i am 60, 5 10, 82kg ,married 40 years and have a heartvalve problem and take medication, warfrin etc. i am active and still working as a concretor and able to maintain an erection without tablets at this stage. we have sex 1 to 2 times weekly at my asking. i look at porn and masterbate not less than twice a day and have told my wife who genuinely does not mind. we have always spoken honestly and openly to each other about sex,we have never discussed this with anyone else.my wife lets me have quick sex to please me, there is no kissing,cuddling, foreplay, or intimacy. my wife say,s there is something wrong with me wanting sex all the time. what can i do to stop this craving?
