There is nothing wrong. As her husband you should make sure she is sexually pleased, even if it means that you have to retain the services of one of us (or in your case, threes of us stallions per week), you gotta keep the wife happy if you want to keep a "happy home".
As far as the daughters and granddaughters, be sure they are of legal age, get your "morning after pills" for them to take and contraception and be more open in the acceptance of the bulls or stallions stopping by if the girls feel they have a "keeper" (very likely they are not "keepers", but the daughters respective "flowers" (sexuality) have to bud some way or somehow, it might as well be under the guidance or oversight of their parents or grandparent. We as a society already KNOW what it is like to hear that white women/wives are not acquainted with the experience of NOT having BBD, so start exposing your daughters and granddaughters as soon as they are of legal age to marry, and consider the experience as their at home "sex education lessons". They will be glad you did!
