does he have to wear a condom?

Lizzie
Me and my boyfriend have been together almost a year now and know each other quite well personally and sexually. Whenever we do have sex he uses a condom about 80% of the time. I'm on birth control which I take my pill every morning and never miss one. We were just curious if we had to use a condom? I don't want to sound weird I just like the feeling when he cums inside of me.
