Bi-curious. Not sure?

Hi all,I’m wondering if anyone can give me advice on my situation. I’ve been a hetero my whole life but recently I’ve fantasized about pursuing gay sexual relationships. I actually just signed up with Grindr and am astounded by the amount of messages and taps I’ve received. Its nothing like straight tinder.At the same time, I’m incredibly anxious of how a hook-up with a guy would affect me. I don’t want to be openly bi. I don’t want to pursue any type of relationship with a guy. I just want to hook-up. What do you guys think? Its something ive never done, and am anxious to do. I dont want this to come out public and don’t want it to haunt me for the rest of my life in case i regret it or its a bad experience.Any advice please? Thank you.
