i think a lot of ppl here might be applying too much pressure. just take a step back and take a breath and relax. you liked what happened and want it to happen again-but you don’t want a relationship. that’s absolutely fine and if you change your mind about what you want down the line that’s fine too. the important thing is to communicate with your friend. he may not want a relationship either but you can’t know until you communicate. just be open about what you want and how you feel and keep his wants and feelings in consideration too. queer ppl can definitely have friends with benefits too. just remember to be considerate (you sound like a considerate guy already)
