I am horny - how do other pregnant women relieve their sexual tension if hubby is not in the mood or available. Masturbate?

Husband gives in to me all the time. sometimes more than once a day. he said he was enjoying my unusual self during pregnancy. but he does freak out esp during 3rd tri. he worries about the baby "seeing" his penis esp when all our kids are girls. and when baby kicks or turns when we are having sex. haha.
