So you want to lower your sex drive AND you are on a mental health website which makes me conclude that you have a mental illness. Well, there are lots of psychiatric medications whose SSE's (sexual side effects) include driving the libido down to zero. Being depressed helps, too (actually, helps a lot). Depression is not something you can will to have, but you can try various psych drugs until you end up with no libido. SSE's are common, it is just that the rest of us here are upset about them and you seem to seek them. I must say it would be a highly unusual motivation behind the desire to try various medications basically in the hope to get a particular side effect, but why not?

And no, there are no orgasms that are too easy - whatever gift you are given in the form of your orgasms is just right for you. But if you truly want longer solo sex you may want to try condoms with an anesthetic which will prolong the time to your climax.
