I think the combination of friendly, interested, nurturing and massive norks is probably what does it!
Yes, a lethal combination 
I'm interested in the definition of 'friend' too. I have male friends that I've had for a long time, either exes or guys I ended up friendly with. How do I define a friend? To me, it would be someone I'd text to see if they could go to a movie, out for a drink, meet for coffee, out in a gang etc. But because I have a family, this is not a regular occurrence... it just can't be because my family is first priority and I'm not free to do a lot of socialising.
But the whole thing of getting new male friends when you're already with someone and have DC etc is a different ball game, partly because of how society sees it. There are lots of other factors to consider.
OP hasn't given much information but I'm not seeing 'friends' in her OP according to my definition of the word, I'm seeing her chatting to men, exchanging numbers at an early stage, maybe becoming too friendly at an early stage, doing the 'I'm such a wild child' thing... sorry but that's not friends even though OP might choose to use that word....
I'm not judging the OP, I just don't think she's looking at herself objectively. Also, she's said every man she tries to be friendly with hits on her. So we're saying all these men are twunts then? Really?
