Hi I'm 17 my boyfriend and I have unprotected sex...I had my last period on June 18th-22nd and since the my boyfriend and I had unprotected sex on the 28, 30, and the 6th of July...ik that precum can have sperm in it n that you can get pregnant from it but my boyfriend has some sort of prostate problem I believe...he is unable to ejaculate...sometimes he says he can feel it while in sexual intercourse but then it just goes away and he can't...so as I was reading...precum can have sperm from pre ejaculations but he never ejaculates. So I would like to know...would there be sperm in his precum even tho he never ejaculates? I'm just the slightest bit worried because I should be getting my period today. I have been stressing out alittle lately...but I have been getting very tired...lower back aches...and lower cramps..so I feel like I should be getting my period but I'm just a little nervous. Can you please help me out please? Thank you..message me or something if you have any answers.
