Sending Husband Sexy Photos

We haven't had sex in awhile and I'm fucking horny. He just got off night shifts and last night I took some sexy pics that actually came out good. (It's rare I'm satisfied with pictures of myself.) I've never actually sent him pictures of myself. When the hell do I send them? While I'm waiting for the kids to get out of dance? While I'm sitting next to him on the couch? Help a girl out!?
