Is this normal?

So I am 16 and I have started to become sexually curious. My mom knows and is getting me on birth control next month. But she doesn’t know all of what me and my bf do. We only do stuff at his house (because we have more privacy there) and we never have sex. We mainly do hand stuff ( him fingering me and me giving him a handjob) when we do stuff we always do me first then him so we don’t risk gettin him cum near me. Then we usually both wash our hands a second time and wait about an hour or so to make sure everything in the area is dried up Incase we missed any cum.

Well recently my bf and I have thought about taking it a bit further. I don’t want him to start doing oral on me but I am considering giving him oral. He always showers right before I come over so I know he is clean down there. I tried to twice so far and idk if I’m comfortable with it. Every time I come home afterwards I feel guilt for what I did and get nervous my mom will somehow find out and punish me. He said he is completely fine waiting to do that stuff again. But I’m just conflicted.

While I don’t feel completely comfortable doing it ( and his cum doesn’t exactly taste good) I figured it would be better than a hj because then there is no risk of his cum getting near me because it doesn’t get a chance to get on the blanket or anything.

Is this ok? Any older girls can y’all please give some advice. Thank you in advance
