TIFU by putting my face in my Grindr profile

Well this is what I get for experimenting sexually with my partner. A few months ago, my (21M) girlfriend (19F) admitted to being turned on at the thought of watching me with other people. Since March, we’ve only fooled around with one other person, who is her roommate. Now, being bi-curious, I proposed to my girlfriend that I do things with a guy in front of her and she was all for it. As a result, one fateful evening, I downloaded the best app for such an occasion; Grindr. Without thinking, I put a picture of my face on my profile without thinking much of it. As you all ought to be expecting at this point, this was my fuck-up. One coworker of mine, “James”, is openly gay. (Should also be noted that my girlfriend and I work together) Now, prior to this incident, I was under the assumption that James had a boyfriend. It wasn’t until I pulled up to work for the day that I saw his face in one of the profiles. Immediately my stomach sank and I blocked him, hoping, PRAYING that he didn’t see me on that app. All goes well until another coworker of ours, “Maddison”, approached me in private and says “Hey so… James says that he saw you on Grindr?” Uh oh. So, within a few minutes, not only did James recognize me on the app, but he also told some of our coworkers? My girlfriend, of course, finds the situation hilarious and plans to play it out as if she didn’t know what was going on. I, on the other hand, am having a bit of a heart attack as some of my friends think I’m trying to have an illicit gay affair behind my girlfriend’s back. I guess only time will tell how this whole mess turns out. I think I’m gonna avoid experimenting with guys for the foreseeable future, though. TL:DR; I used my face in my Grindr profile and my coworker thinks I’m cheating on my girlfriend.
