I would say women can be as bad as men....so it depends on the woman, just like it depends on the man....
I had a woman in college come up to me after having been saying Hi to her in the mornings for a couple weeks, ask me to go to lunch with her, mind you we have only been saying HI did not know her name or anything else about her....So at lunch we have nice chat and then she asks me what I am doing this weekend and I told her no big plans, she flat out asks me to come up to her house and have sex, and then asked me what kind of protection I liked...So pretty straight forward and aggressive...
Different college, was working out in the weight room, and had this young gal watching me, every day I was lifting she was there, finally one day I was having trouble with my bench and there she was to help spot me which I thought was cool. Well she then stayed right with me thru the whole work out, not saying anything just giving me smiles when I looked at her. At the end of my work out she asked me what I was going to do next, and I told her go back to my apartment and take a shower and probably go cruise the mall. She asked if she could come back to my apartment and wash my back, and then let nature take its course...I smiled at her and said how about a hug for now, she latched onto me like a vise...She was persistent on seeing me at the gym, but I didn't have any attraction to her.
Had another young lady at the school library that I had been talking too off and on, and there I was down on my knees looking for a book, she comes walking up in a tube top and short blue jean skirt, I look up and see her looking down and smiling at me, I said hi, and told her I was looking for a particular book, then she said I have something for you to look at, and when I looked up to say something she grabbed my head with both hands and shoved my face into her crotch, she had panties on, but still, then she let go of me and laughed as she walked off....
I could go on, but I would say that women can be passive or they can be aggressive when it comes to the opposite sex. Just remember your husband came home with you, its not like he was trying to get laid, and its not a bad thing for him to flirt, you get to benefit from the stimulus, well probably not that evening since he knew you were pissed...Also as men get older we like to know we are still attractive to the opposite sex, its just our way of saying Cool I am not too old out of shape yet that women don't find me attractive...
However your husband should take it as a compliment that you got upset, just tells him that you love him and want him to be your very own, which is not a bad thing to know as well. Maybe you should have slapped him on the ass and told him to knock it off playfully and told him I will be taking care of you when we get home and gave him a seductive smile, that would have woke him up, and that would have let the young gal know that you can look but I am going to fuck him when I get home and you can't.
