So my boyfriend and I didn’t have full penetration he touched his pre-cum before fingering me, we made out for ten minutes and then after he rubbed the outside for another ten minutes and then he went inside and I’m pretty sure there no way that I’m pregnant but he made me take a plan b pill. The symptoms are much like pregnancy symptoms and I’m a little scared. Is there anyway that I could actually be pregnant by a finger or how fast would the sperm die once its exposed to air?
