Scared (Sexual experiences with 2 ex’s and now bf)

guys sooo story time so a long time ago like 2 or 3 yrs ago (with my ex) I had unprotected sex anal sex like 2 times and he tried sticking in the vagina but I didn’t really let him f me in there only the anus.. i heard rumors that he could had possibly had cheated on me with someone else n I thought what if he did the same with the other girl.. (p.s. at that time I ask him if he did cheat on me he always says no which made me a bit confused with everything) I didn’t have symptoms or anything but still it got me a bit scared until now.. after a few yrs has pasted I started dating another guy (which is my other ex) but we mostly did it protected (but he didn’t stick it inside of my vagina nor anus but he tried with a condom) but he did oral little bit than stopped… (no symptoms) and the guy I’m dating now which we didn’t have sex yet but he touched me down there n well also did oral sex but now my vagina feels weird…. (Sorry for a lot of information)
