In this post, I'll address attraction. Visual is important to women, but may not be the first bait.
Things I wish young Hetero males knew today:
If you have a distinctive voice, keep it - I'm not saying exaggerate it, but keep it. There are women who almost snap their necks when they hear a distinctive male voice, and try to locate it. Your voice may lead a woman to look closer at you; an "almost" average-looking male can be unbelievably attractive to a woman, if he has a voice which is appealing to her. (And you should probably use that voice during sex; words matter less than your sound and breath ...)
If you, or a friend of yours, finds a "product" that works with your natural scent, be it cologne, soap, or shampoo, mega-purchase it!! Women's sense of smell is generally better than yours, women can really dig a great (masculine undertone complementary) smell.
Posture matters! Casual slouching on the couch is one thing, but women DO notice your macro physical presentation. Head high, shoulders back, stand up straight! Own your body! If you accept it, more than likely, some women will, too.
Wear clothes appropriate to the situation, and your body. Crap clothes for heavy physical labor - HOT. Casual, well fitting clothes for BBQ - HOT. Tailored suit (screw the strained buttons look: gag), with correct material & pants length, for serious, public display - HOT. You want a woman to look good for you, return the effort & consideration! Look good for you and your type!
Invest in finding a hairstyle that suits your hair, head shape, and face. Once you find it, it can serve you for DECADES. Update per fashion ONLY if suits you! Discount this at your own peril.
Self-conscious/self-centered men are a turn-off!!! If you aren't comfortable with you, why should she be? If you are super absorbed with yourself, what do you need her for? (Go fap to your reflection!). If you give less than 60% (MINIMUM) of your attention to a woman, at any time, you're at risk of losing her to another male, or, to herself. There are exceptions to this rule, but do NOT dare to assume those exceptions can be frequent or common. You're dealing with a woman: you're more likely to receive back five-fold what attention/adoration you give, so risk versus reward... (Are you smart enough to figure that out?!)
Do you know the definitions of ethics and morals? Have you any? These can be fundamentally important to a woman regarding relationship potential...
Get too comfortable, take the woman for granted = kiss her ass good bye. You CAN trust MOST women, BUT, (here's the secret): women are people with feelings, too. (OMG). Take a woman for granted, neglect to romance her, fail to make HER KNOW you appreciate her, and you WILL lose her. (And if you don't, you should lose her!). In short, if you drop the effort that she understands, it's your fault the relationship failed. Men are the "leaders", right??? (Alternatively, if she is the very rare hellhound, it's up to you to improve your discrimination. Deal with it; you're not the only person who picked wrong once.)
Step up, do the work, put in the effort, recognize her devotion and contributions: for the win. (Again, multi-fold returns, practically guaranteed, if you're in relationship with a woman.)
PS Mgtows/MRAs: So enough with the whining and finger pointing, are you really blameless? Look again. Yours is not the only perspective that matters, it takes two, yes? If you got burned, well, you picked her; chock it up to life experience, choose better next time. If you slacked off, you got what you deserved, IMO, so FOff.
