I like to have sex but not as much as my boyfriend


He likes to have sex every day 2-3 times a day.... I like sex one time a day either every day or every other day. I don’t want to be rude and make him think I don’t want it but we already have two kids and I’m not on birth control. I feel like if I don’t give him what he wants then he’s mad but I also don’t want to feel like a sex object. Help me what do I do!?
