Thoughts on friends with Benifits ?

I'm just curious what your thoughts are , everyone says that someone always catches feelings.. Is that true ? Comment your experiences please ! I have one now but I really don't think we're gonna catch feelings , especially cause it's literally just sex , we don't txt or anything like that. We do send thirst traps though , too keep it interesting. I think I'm just worried now cause usually we do it like every 3 weeks(😑) but now I feel like that's starting too pick up & im alittle nervous cause I had a crush on him in Highschool && it's the best I've ever had 😩
