popa: If it can be dealt with in marriage (and in fact he better be prepared to deal with it), then a bochur can deal with it with a bride-to-be – as much as a husband can deal with it with a wife.
And what if a bochor is 29 or 32 or 35 and cannot get is fantasized bride? Can he lower his expectations on looks and weight? If so, so can a 19 or 21 or 23 year old bochor. Especially since all of them better be prepared for unavoidable changes after marriage.
And what about old age? Will the husband to be divorce her when she hits 40 or 50 or 60? She ain’t gonna have those looks anymore. He can deal with it then? So the bochor better be prepared. And if he can deal with it then, he can deal with it now.
