Some overgeneralizations, that someone will undoubtedly validate: Men do the lion's share of the asking to dance, because of archaic cultural norms. Because men are supposed to be "superior" because of those same cultural norms, beginning male dancers are often intimidated by skillful female dancers, and won't ask them. "Skillful" male dancers (in their minds, at least), take advantage of that "skill" to dance with and try to show off to young, attractive, beginning female dancers. Following these common observations, and the fact that at most venues ladies significantly outnumber the men, it it is harder being a follower than a leader. If a beginning lady summons up the courage to ask me to dance, the very least I can do is to cheerfully accept her invitation and try to show her a good time on the dance floor, regardless of skill level. Yes, I do take the risk that some slightly creepy ladies will take that first acceptance as an invitation to hunt me down for every dance, and I will have to find a way to gracefully deflect that.
