Gave It Up

So i’ve been dating this guy off and on for two years. We recently got back in the right space but i didn’t consider us together. I also started a new job and my assistant manager is a flirt but i am too and didn’t think much of it. He eventually was serious and in the spur of the moment we ended up doing it but it was my first time and the guy that i’ve been dating doesn’t know but we always talked about losing to each other. He’s inexperienced and doesn’t necessarily please me fully so i don’t feel bad about having my first be to someone experienced but i do love him i just don’t want him sexually.
