sounds like you need to do two things:

1) tell your husband you don't like being called a b**** just because you don't want to ride
2) tell him to appreciate his wife for who she is... and not who he wants her to be

... and as for the saddle, honestly... if you were really into cycling (and that's perfectly okay that you're not!), you would have found one already that worked. I somehow think the saddle is not the real issue here
