I gave my bf a blow ** but I did NOT touch his penis. He didn't ejaculate, but there may have been precum. He urinated and showered multiple times before this. About 15 min later I touched my lip with my hand (there wasn't saliva). I then started driving and grasped my steering wheel and touched other objects. Then 10 min later I wiped myself. Then later my boyfriend and I kissed for a little bit. About 45 min to an hour later I brushed my teeth and washed my mouth out. I put my hand under the sink for a little bit to take a drink of water, then I put my hand to mouth. I then rinsed and spit out the toothpaste. I don't remember if I wiped my hand or not on a towel, but I then touched some soap and started wiping myself down there. Could that make me pregnant? Please help, I'm really stressing out over this. I took a pregnancy test and it said negative but still.
