Kristy,
I donīt know but I donīt think sending pictures of interracial sex to your husband is a good idea. He could open them, enjoy them but not share what he thinks with you... Maybe you have to see how sex is in your marrige, how you feel the creativity of your husband about sex... Does he seem to have some kind of sexual fantasies too? Does he enjoy porn movies? Sex is so important in life that is not wrong to talk about it in a open way in a marriage and so you are going to find out what he thinks... tease your hubby, dear
let he knows the hot woman you are.
I believe that is totally normal to have sexual fantasies and it doesnt mean you are going to make them real, so I donīt think it is a problem to share them with your husband... probably, he must have fantasies too and you both can have a great time sharing them
why do not invite your husband to a sex shop or let him know you would love go there? Once there you could look for some black dildos (that ones that seems a real black cock) just to see his reaction (something to tease him...)
Women know how to tease men
I wish you luck too
