I'm not humanodon, but feel similar to how he does.

I cannot imagine how having sex can increase your social status

The only people sex increases social status for are maybe high school kids. No one really gives a shit passed that time in our lives if you've had sex or not. Sex as a social status is a temporary thing to immature people. I don't see sex having anything to do with social status.

or how need for sex doesn't make you stressed

It only makes you stressed if you let it. I hate to use the term "don't put the pussy on a pedestal", but it's an anecdote that applies here. It can only stress you out if YOU are putting to much weight on it in your life. Personally, whether I am getting sex or single and not getting any, I'm not stressed about it either way.

Also, one other thing you said above that I disagree with too...

attraction - does not explain why people need sex. Many people are attracted to power, wealth, cars, things, but I have yet to see how you can make an intercourse with a car, coins or power

Attraction and sex are natural and things humans, and all creatures, experience. Power, wealth, cars, and more modern obsessions are not. These things aren't proper comparisons.

I have no problems with how you want to look at sex, by all means, we're all entitled to our opinions. But some of the ways you explained it seem to be stretching a little and based in personal insecurity. If you don't like sex and don't want to pursue it, I'm cool with that, but like you admitted, you're definitely coming off as "anti-sex" and don't seem to get why anyone would engage in it.
