This is so backwards. So you're not friends with any women you sleep with? Do you hate them or objectify them? Why the hell do you sleep with them then? You think people that have been married 30 years aren't best friends AND banging each other's brains out?
When a woman likes you as a friend she'll tell you anything. If you're not some sensitive insecure jacka$s then you'll assert your boundaries in a charming, effortless way so that these interactions are always enjoyable for you.
Female friends invite you places with other women, hook you up with friends, disarm other women, put in good words for you, play excellent wing women, the list goes on.
A guy with options. Why would it bother me when I have 5 other women that are showing interest and want to fuuck? I'm happy for it to resolve faster, so I know which circle to put her in my mind, and how to treat her so I can focus my sexual energy on other women. When you say 'k' like it's nothing, it drives women with interest nuts, especially if she sees you interacting with others.
Some posters show their age in their profiles, I'm in my early 30s and have no problem with women.
This is backwards. You should be the one happily putting girls in the friendzone. Get this weird predator mentality out of your mind, it just fuels your desperation. When a girl friend asks for favors or whatever and you sense she's trying to take advantage of you, simply create distance and focus on women that you do enjoy. It's not rocket surgery.
Fuuck or get out is what a guy thinks about a woman he doesn't like. Why the hell are you trying to fuuck a woman you don't like? Maybe in some spur of the moment drunk hate fuuck, but otherwise wtf are you doing talking to her in the first place? This just reeks of desperation.
If being friends with women makes you feel weak, go work on yourself and learn to assert boundaries until you don't give a fuuck, it's really that simple.
