y girls allergic to marry old man?

Really? for my self am more prefer marry with old man. Cos i think old man more can understanding young woman,more patient. not like young man, that why my bf have different age with me 20yo. make me more happy cos he more patient, understand, care, to my self.

My guess would be the diffrence in age might be a problem when raising kids, you want someone that is fit and can be there for them. Not someone who could die soon and leave them to be raised by a single parent. Another reason could be that they are unattractive or something. The only time I ever see younger women with older men is usualy when they have lots of money or something.
