I have about 1 min to respond because work is currently blowing up.
But Coconut is right. It has nothing to do with dominant sex. It has to do with being confident, handling situations, making decisions.
For example, my cousin is an alpha female. She makes the money, decisions, ect. Her H is fine with not taking charge, only doing things when told, not making plans and leaving it all up to her. Well, I won't get into the specifics of what's going on there, but, she is absolutely and completely turned off by it. Actually, after all these years, kind of disgusted by it. She a man who takes charge (not bossy) but gets stuff done is attractive.
I am going on a date Friday night. He told me where and what time and asked if that worked for me. Instead of "we can do whatever you want"
I gotta go, but I hope this clears it up a little.
