My friend is the WHOLE package, but can't find a decent guy to get into a relationship with?!?

My friend is stunningly attractive/sexy, intelligent, and has a great bubbly personality...she goes on dates all the time, mainly with guys from online dating sites. She will tell me about how they all showed so much interest in her, after one or two dates, but then she never hears from them again?! she tells me how they all try to practically jump her at the end of a first date...she dates plenty of men who are half as attractive as her. Are these men intimidated by her?
