if u give a guy oral and finished in ur mouth. kisses u and he returns the favor 2 hours later can that be a risk? dumb question ik but i was just wondering

edit: since personal info is so important might aswell say something i guess. im 17 about to be 18 in a month. me and my boyfriend have been together for 4 years both of us are clean. and i have crippling fucking anxiety. i was never taught anyything about sex as a kid. blaming both my mom and the schools because they both fucking suck. to add ontop of that i was raised to fear it. i was told it only takes a dick to get you pregnant. I've been on birthcontrol for 9 years but wasn't told what it does to the fucking body. so basically i was failed as a child. thanks to the women who weren't judgemental and tried to be atleast understanding. really appreciate it
