we just have sex 3 days before my period is gone, and we did it again the next day, and we did it again the next 3rd day. but the 3rd day that we have sex, my period is over and he withdraw his sperm cell inside of me. is there any chance for pregnancy?

I didn't wash my hands after touching my sperm and I rubbed it on my shirt and I fingered my partner , can she become pregnant ?

Hello.
Follow up question,
Does sperm die as soon as it contacts with rubbing alcohol? (70%) and hand sanitizer? I only wiped some parts of my hand leaving few with sperm then I used hand sanitizer and rubbing alcohol. After a minute or less i inserted my finger to her genital (my finger was still a little moist that time). I am pretty sure i used it thoroughly around my hand and i used it three times. Is there any risk of pregnancy?

Thanks :)

Good Day.
i come on my underwear and we rubbed ours together but my girlfriend also wear underwear. Could it be any chance of getting pregnancy?

Good day.
my partner and I were touching each other and later on i came on my hands. i wiped some with tissue and used hand sanitizer and rubbing alcohol 3x then after a few mins i inserted my finger in her vagina for around 10 seconds. is there a possibility of pergnancy?

Hello. Okay so I never touched his penis directly.his whole penis was inside his underwear. I was touching it from the outside To stimulate it. Then he did inform me that he might cum and eventually he did. But he was trying his level best to hold it back in. So what I am saying is that as I saw it come out inside his underwear ( the stain was slowly appearing like the way you would expect a drop of water to expand on a tissue and since he was holding it back, it was evidently slow) Moving on, when he did say he was about to, I removed my hand almost immediately. But lets assume worst case scenario and say I touched it for just two seconds maximum. Alright after that we got off the bed almost instantaneously and went in separate directions, like literally. No further physical contact WHATSOEVER at all. So then I went to the front door of my house to open the gate. Even then we Never touched each other. This was like about three minutes after that cum incident. So he left. Then I went to the kitchekitchen and washed my hand for only like three seconds or less with water only (no soap). You could say it was for a brief momenT. Ok after this, like ten minutes I returned to my bed and I touched myself, including the vagina but not too deep and just for a short while. Okay I've explained everything in detail. I humbly request you to understand what happened exactly and tell me my likelihood of conceiving. With any proper reasoning. I'm sorry if it sounds ridiculous. But I want to be sure. What is your honest opinion? And any logical reasoning behind it?
