burning after getting fingered???

me and my boyfriend hung out today and usually when he fingers me, he can only use 1, and 2 if i'm really in the mood... but today we tested it and used 3😬 it felt a little uncomfortable but not enough for me to ask him to stop. that was maybe 3/4 hours ago and i've used the bathroom twice since then and both times it has burned/had a sharp pain when i pee. could that be just from me having more than average in there? because i doubt i could have had an infection or anything like that as i was fine before he fingered me
