I need advice.

Ok. I am turning 16 soon and my boyfriend is 16. So me and my boyfriend have been together for almost 11 months. We have started to do sexual things. The other day he put his fingers in me and that’s as far as we get now. I feel like I’m ready for sex and I’m on the pill. I went to my mom a few weeks ago to try and ask her about what to do but she was getting mad at me for even mentioning the word sex. I trust my boyfriend 100% and I know I’m 100% ready but we can never do anything that far due to my mom not letting us be alone unless it is to clean. Any advice? Do not comment anything along the lines of your too young or don’t do it. I’ve already stated that I feel ready and would appreciate the respect and professionalism.
