What you said isn't wrong but it's different. Sure men want to attract a lot of women because they are seen as more of a man because of it. But it ain't necessarily the fact that they can attract a lot of women, more so the characteristics of the man his aura, personality, confidence, leadership qualities etc. If it were based upon how many women a man can attract, then men would perceive male models as the most manly because those men attract more women than the average guy.
And it ain't even about attention, more so sex. How many women can you get in bed? The average guy isn't even having sex like that. Most men die with having less than 10 sexual partners. Most dudes aren't really thinking about that PUA bullshyt and how to attract a lot of women. It's the dudes that really struggle with it that do. Most dudes get girlfriends, and some the occasional fling here and there if not at all.
The male friendzone is different like you stated. It's sex only, not for attention. And as for a man having female friends that he knows lowkey likes him it's different, because he isn't leading them on into believing that he likes them, nor is he using them for attention or favors. I have been on that side many times before and I never used them for anything, I didn't feel some type of ego boost or hit them up when my phone's dry like women do. These guys are often good looking, whereas women can be average and still ahve men in the friendzone.
Women and men view attention from the opposite sex differently. Attention from a woman without sex is worse than no attention at all. Whereas women are more than fine with getting attention from certain men and not having sex with them.
There's a difference between a need for human interaction (one of maslow's hierarchy of needs) and a need for attention from the opposite sex so you feel sexually attractive. Do you think dad's with beer bellies are focused on being sexually attractive to women? Most men don't care about the attention of other women once they have a girlfriend, wife, etc.
