Hi! I have questions regarding risk of pregnancy. 1) when my girlfriend touched my genitals (male) that have precum produced, after that she might have forgotten that she had touched it, then she put her finger into her pants and touched the outside of her genitals. 2) I was trying to adjust my underwear using my thumb by sliding into my underwear. I'm sure there's some precum, but I'm not sure I have touched any of the precum. Few minutes later I rubbed my thumb against my middle finger. Then after that I touched the opening of the my girlfriends genitals. 3) if she's having sexual arousal for the first time ever, would it cause her period to be delayed? This happened on the 21st day of the cycle, which has average cycle of 30 days(+-). So, would the situations described above post any risk of pregnancy? What's the chances?
