Here are some options, try to prolong the orgasm, for example more foreplay, keep it going, also on a serious note be vocal upon an orgasm. It has been proven that when you release vocally upon having an orgasm, you have a more powerful orgasm, just like when a person lifts weights to achieve more power they yell or grunt, they release the power, also try to go without sex and masturbation for a longer period of time, that will help with the amount and pleasure. And alcohol also contributes to incompetence, so ease off the drink.
First of all, don't take any drugs again to get that strong orgasm feeling again. Maybe you should try experimenting with sexual possitions with your wife, role plays, extensive foreplay and also buy her some very sexy lingerie that she could wear. Also there are some lubricants that are supposed to maximise pleasure during intercourse.. Hope i helped, good luck.
hey dont do herion anymore and eat right to achieve a good feeling inside, maby add some herbs to the diet aswell for enhanced mental health.
and if you apply pressure to the area of skin between your anus and scrotum then itll make the orgasm last longer since the semen is forced threw the tinitest space made possible by you, dont be tempted to hold it pressed shut becuase at your age and state you might cause some problems...i dont recommend doing that for sexual enhancement either.
