HI everyone, I have a situation that worries me, 4 days ago I was with a woman, and I masturbate her on clitor and inserted my 2 fingers for second into her vagina and she stopped me and told me that this such a dirty act to do, and then I masturbated her clitor and little under it around her vagina but I did't insert my fingers again in her vagina, then I cleaned my finger with 2 wet clinex, and then gave her wet clinex to clean her clitor and her vagina and then she masturbated me but didn't touch my urethra (just on the skin of my penis), but what worry me that when she cleaned herself, maybe some of her vaginal fluids remains on her hand, and when she masturbated me maybe these fluids can goes in skin because of friction, but she didn't masturbate me hard, it was easy and didn't pain, I checked my penis, I didn't see any wounds or broken skin or anything, can I be infected with any STD through this exposure?
