u/CheckItchy

We have been friends for years and have only made out before. Just want to know how to keep the friendship after and how to have it not be awkward before/after? We are 18M and 18F and have had sex before but not with each other, the main concern is the friendship continuing, the before being awkward at times can happen and I am not as worried as i am about the friendship. I want it to be a good experience for the both of us. Any advice or tips would be appreciated
Thank you in advance
