Why is it considered secret, or private not to share your family with your new male friend?

Some girls don't like there parents knowing. It could be embarrassing, they don't want to ruin there time together if there parents stuff up the whole meeting thing and, for some girls, they have to consider there... dads. Yep, daddy's little girl. Every girl is different when it comes to... FAMILY MEETINGS WITH YOUR NEW MAN! Hope this answers your question

You don't want to introduce a male friend to the parents until its serious... parents tend to want to do a lot of questioning, and also tend to jump to concludions.

I can vouch for this being a guy, my first date with ym previous girlfriend I was picking her up from her house, she was late and I got stuck for 15min alone with her dad... meeting a girls dad can be really intimidating because there daughter si there little girl and they want to make sure she has the best that there is, sometimes an unrealistic best, but who can blame them, being a guy I know I'd want the best for my daughter if I had one to.

Moms on the toehr hand I've never had a problemw ith they always seem to like me, I think the moms are more relaxed because they see the events from a woman's point of view not a guys.
