You might worry what she'll think of your clothes, hair, mood, or your place. But she doesn't always care about this stuff as much as you think.
There are many things men often think women care about... that they really, absolutely do NOT.
It's one of the biggest mental blocks that holds men back with women. Guy worries about something women don't care about, and proceeds to not try. "I'm too X; she won't want me. So I won't try." "I'm not Y enough; she won't want me. So I won't try." Meanwhile the reality is she doesn't care about X or Y, or not to the extent you think she does.
I have a friend who was prolific with women years back and took some time off from proper dating. He's now getting back into the swing of meeting new girls. The other day he had a sexy girl eye him up hard... another guy was hitting on her friend, and this girl wanted my buddy. But he had a few reasons to not go for her: he had to finish some work he had a deadline for, and also... his place was too dingy and dirty. He'll switch to a newer, nicer apartment in a few days and prefers to wait to pick up until then.
The work thing is understandable. But the apartment thing stuck out at me.
Because women (most women) do not care about a dingy apartment when they are into you enough.
I have slept with plenty of women in small, crummy apartments or hotel rooms.
I have shagged women in friends' filthy, crumb-filled, stained sheets that hadn't been changed in months.
I have shagged women on the dirt outside, shagged them on rocks, have gone raw on countless women I just met (most objections I've gotten to that have come during or after, rather than before). I have shagged women after not having showered for a week. I have shagged women when I had body odor they complained about (but not enough to stop the sex. Also, just for the record, my body odor is usually not bad. Not sure why it occasionally is. Diet? Stress? Who knows?). This is all stuff about which a whole lot of guys would say "Oh no, I couldn't possibly have sex with her now, because X!"
Women will tell you they care about all this stuff. But mating itself is a dirty act, and once a woman decides she wants you, dirty stuff she'd have told you would be a deal breaker other times largely stops mattering.
I grew up compulsively clean, too. It took me time to get over that, and to realize all but the most germophobic women do not care about it, when they want you. I get a kick out of dirty lays today. It's a bit of a thrill to be some girl's dirty man. Many guys these days are too tidy to be that for her. (that said, I do usually try to keep things clean. If only for my own peace of mind)
However, this article isn't just about being a dirty lover. It's about ALL the stuff guys use to talk themselves out of taking action... yet that girls don't actually care about.
There is a lot more stuff guys think women care about that they don't than dirty apartments, sheets, showers, or smells.
