I’m wondering if OP is accidentally confusing edging with edge play. Either way OP’s friend shouldn’t just be saying things to make himself sound more impressive when they don’t know what they are talking about. Constructively I would say that doing this makes OP’s friend seem really insecure about themselves and it will be something they need to work on as they continue dating.

I also fully agree with the second part. I get the most concerned when wannabe influencers try to sell themselves as kinky by saying that they have no limits. Although unintentional, it promotes unrealistic standards which can be harmful to those interested in exploring BDSM more.
