not very likely assuming his vasectomy was a success. i have a suggestion: why don't you keep "fooling around" and capture some of that ejaculated semen so it can be properly tested at the lab for viable sperm? this way you will know for sure for any future sexual mishaps.
embarrassing question: is pregnancy possible? . my husband had a vasectomy in april or may. i am not on birth control and we have not had intercourse because my husband has failed to return semen specimens in a timely manner; therefore we do not know if he is sterile. however we have fooled around with him being completely nude and me wearing thin underwear. he has twice ejaculated on my underwear at my vaginal opening. i am concerned about the likelihood of pregnancy under these circumstances. any info you can provide is appreciated.
