Why Do Gay Men Like to Swallow ?

So Iam DL . I’ve recently discovered grindr and I love it . It’s like an endless supply of free blowjobs. What makes it even more fun is the guy actually enjoys it. It doesn’t feel like a chore to him and they actually have fun sucking dick . You can see the joy on their face. They get even happier if they get a nice big load to swallow. My Question is, why do gay men like to swallow? Why do you like to swallow? What was the biggest load you’ve ever swallowed.
