Im lowkey scared

My boyfriend and I are very busy people, sometimes we don’t have much time to interact other than through social media and school. This may sound weird, but we plan our sexual interactions. We haven’t really gone past handjobs, but this week I’m thinking maybe a blowjob. We’ve talked about it before (haven’t had the time to actually do it) and we both consent.

Any advice?

I’ve never done this before
