Shooting into guy's mouth and face

I like to shoot my cum into the mouth (or generally face) of other guys. Some guys on Grindr are happy to comply. They visit me at my home and then we do it. I like it when they swallow. Because eating cum is considered somewhat risky, I always pay attention not to touch them very much and I also do not perform sexual acts on them, but sometimes they like to lick and touch my body while they jerk off after they swallowed my cum. Is there anything I should consider or be aware of? Do you also like to do this and how do you plan/proceed?
