Yeah, she bragged to Lena and Holly about it during their daily girltalks. She also showed them pictures/movies because that way Eva could plausible release Ivy content while still keeping Lena's PoV.
Sarcasm aside, that way Ivy could plausible be that successfull superslut who never has problems bringing guys home and be a role model for Lena and Holly, who apparently have relationship issues and trouble getting dick.
Seriously, the equivalent of GGGB, Jessica, sold the superslut because she was occasionally fucking dudes. She was already a fuckbuddy of Jack while we still don't know if Ivy ever had something with Axel or not. Jessica got into detail why and how she fucked dudes (money, tatoos, bordedom, attention, powerplay) while Ivy is just holding her distance through Stalkfap. Jessica asked to sleep by Ashley because she had trouble with one dude, she could sleep with Jack and/or Ashley during the Jack/Tyrone date. Once you live with her, she was occasionally bringing home guys like Kevin, could participate in Tyrones pool party and she was fairly quick a threesome candidate for like Jack, later Dave, Arthur and so on.
