My daughters are too young for BF's, but eventually they will be old enough. I do not think I care about their hypothetical BF's porn usage. I would hope that my daughters, who are both exceedingly hot, would have their sexual needs met by the respective BF's, and if there is some leftover sperm after that, then, OK, let them use porn, why not? I think I would be indiffirent to that. Not that anyone would tell me, anyway, but if for some very odd reason someone needed my opinion, it is that - indiffirence.
