Should every man try to develop 'alpha' traits in such a manner that attracts women? Should every man spin plates?

What if your comparative advantage in men is not in this area? Some of my friends are very smart people, professionally successful, mature, happy, etc. but temperamentally and physically they are not 'players'. They are more like nerds. None of them are promiscuous, but some of them have found sweet girls with gentle personalities like themselves and seem to be happy in LTR relationships with the prospect of marriage/marriage.

Are my friends' relationships doomed to divorce? Would you tell these men to lift and go hit up the bars and nightclubs instead?
