@romantyke i am your antithesis!
i am aromantic, meaning i often don't feel any connection with sex partners other than the physical attraction. to me all attraction towards my partners come from what i see, smell, and of course from whatever i project onto them, which is inevitable. once i start to know them more intimatelly, i still find them physically attractive, but sexually i lose all interest, because that stranger who could be everything I crave no longer exists.
on the matter of masturbation, i share the same habit, but i would not go as far as calling it an addiction, it really is merely a habit. it's simply the activity i chose to spend my free time, but when i am doing something else i don't feel any urge to go back home and masturbate, if i stay several days without doing it it will not cause my body to start shaking uncontrollably or drop my pants and start doing it out of nowhere... so not fair to call it an addiction imo.
just like you, i am pretty happy with this habit, i could have a more balanced sex life, but it costs money to go out and meet people, and it can be emotionally draining, so i only do it very occasionally when i'm really feeling like it.
