Farting during sex?

Vera

Okay so I’m extremely new to sex. I’ve only done it with one guy but it’s been quite a few times. I felt like i was gonna fart everytime we had sex though? it was like a pressure in my butt/stomach? that kinda just felt like i was about to rip one. and i get so scared so i’ve kinda tried to hold it or make him stop for a second. Am i actually gonna fart or is that just a typical feeling?
