How to Safely Explore Slutty Kink

Hello my fellow sweet sluts <3 I hope this is the appropriate place to post this. This account is new but I’ve been a long time lurker of more tame subreddits. Anyways, I recently got back into an old kink of mine: exhibitionism. For length purposes I will cut to the main point and leave history for if anyone asks about it, I am in a relationship and while my partner knows and we do some things, I explore this a bit privately. I so far usually fulfill this kink through flashing my tits online on an anonymous website but recently made a small attempt in person. I also wish to disclose here that for me this was pretty slutty, but I understand that it isn’t for everyone. The other day I left from my office in a thick jacket since it was cold outside as I went grocery shopping and then went home. However, before I left work, I actually took off my shirt and bra and was completely naked on my top half under my jacket. For me it was really exciting to think that I was really exposed around so many people and no one knew. I even loved feeling the cold air blow down my jacket and touch my nipples and how my boobs felt bouncing around in my jacket. For me, this is a safe situation because the security recognize me, but it did awaken me, wanting to explore this kink more (but safely obviously). How could I do that/how have you all tried before?
