improve my skills while on a “break”

my (20F) boyfriend (19M) just broke up a few days ago after a nearly 4 year relationship. it was pretty messy in the beginning due to hurt feelings and what not, but he reached out and we had the greatest conversation/break-up sex ever… we are officially broken up but it seems like there’s a lot in the air about potentially getting back together after 8 months of no contact (super specific, i know). right now i’m not interested in having sex with anyone else and he’s voiced that he doesn’t want me to either, and he won’t have sex with anyone during the time we’re apart. but if we do get back together, besides impressing him with being able to open up and communicate freely, i really want to blow his mind in the bedroom. how can i increase my freak range and skills without actively participating in sex?? 😅
