The scope of things in which I am interested is very narrow, and people rarely are in this range, and if they are they are invariably only there for a brief time, so people in general, including women, sometimes try and do anything to get my attention, including acting deliberately annoying. Sometimes it works, but ultimately it always backfires and I no longer pay any attention to them.
People in general seem to simply want attention, and some people are simply more willing to do particular things to get it than others.
In my experience, men in general become bored fairly easily and so women feel compelled to continually do things to try and maintain a particular person's attention. The genitalia add a certain compulsive element, but at some point most people get bored of the particular form of pleasure generated by the genitalia. It seems to me that at this point the opposite gender has nothing in particular to offer.. What makes women so special that I would want to spend my life with them instead of with men, who I don't find so fascinating as to want to live in the same room(s) with them for the truly personal/self-expressional sections of my life? The only answer is the genitalia, and once the bodily sensations generated therein are no longer interesting, then women can hold no interest.
Intellectual stimulation is nice but personally I've given up on this planet in that regard, at least in this place and time. People can make some interesting things after working on them privately for a while and then presenting them publicly, but even then society by and large rejects anything truly interesting and a person is lucky to ever find these things before they disappear due to disinterest and/or disheartenment. The internet and other democratic-style mediums make it easier to find such things, which is nice. In another thousand years perhaps this place will be more enjoyably closer to infinity. As it is now I don't see why anyone sticks around for long, except out of a sense of fear, fear of death, fear of god zapping you, fear of people laughing at you for not following 'society', which is mostly women laughing at people to try and get them to have sex with them, and insecure men laughing along with them because they secretly wish they were women.
In short: Earth, nice place to visit for a few years, wouldn't want to live here
