hey, i didnt insert my penis into her's but ejaculated in her hairy portion , i touched the sperms with my fingers and after 10 to 15 mins, i inserted that finger into her vagina unknowingly , i read that the sperm dies within minutes so do i have to worry, what are the chances for her to get pregnant and how to avoid getting pregnant if the above case is true, i promise to have protected sex next time and adding to this she has very irregular periods for the past one year
