think I'm catching feelings

This my second time doing the lil friends in benefits . My first time me and the guy was just friends and I didn't catch any feelings but now  me and this guy are like friends with benefits . Oh yeah I'm 18 btw and his eight years older than I am ? start seeing each other and we had sex . the first time doing it I was hooked. I be wanting to be right him every sec but like I don't know . Because I'm not the clingy type but I feel myself becoming one :( & I feel like it's has to do with his age that makes me want him!
