first time help ;)

my boyfriend and i haven’t been together very long (he’s 17, i’m 16) but weve been talking on and off for over a year and he told me was in love with me 7 months ago. a few things happened, but we’re now official. we have hooked up, given and had oral sex, and he’s eaten my ass. we have been talking about having sex (we are both virgins) but we feel ready and are able to have a comfortable conversation about it. i’m on birth control and he would use a condom, and i feel emotionally ready to do it. i love him too, and he’s someone i know will stay around. so i was just hoping for tips about having sex the first time, how to prepare emotionally and physically and how to make it the best it can be. thank you :)
