I masturbated in the morning around 9:45 then took a shower, I don't remember urinating in the shower and I did not urinate throughout the day. 11-12 hours later I had unprotected sex with my girlfriend for about 45 secs before I put a condom on. I know that urine cleans out leftover sperm in the urethra but I was wondering was there still leftover sperm in my urethra 11-12 hours later? And if so, since I only went raw for about 45 secs, how likely is she to get pregnant? It happened on the 14th and her ovulation calculator app says that she is suppose to ovulate on the 17th so she was fertile when it happened.
