Getting werid thoughts

Don't make fun of me when I say this but. Hi. I have always think to myself is my mom pregnant by me or my father? Okay let me tell u the story.Going thru puberty was a little hard for me. Okay I meant really hard. I mean these hormones kept kicking in. It still does. So on the weekend I sometimes do my thing. In the bathroom(you should know what I mean).Look I don't do it every day or every 2 days okay?.Well sometimes but what I'm trying to say is I'm not crazy addicted to doing it. I started doing it at a very young age til to this day.But that's not important.What I'm saying is could it be me that got my mom pregnant cause of what I do ?Or could it just be my dad all along,just a thought I been having ever since I start doing it.Thank you and be mature about this.please take this seriously. Im well kinda worried about it xd.

Please answer me these questions if u dont mind.
Let's say if u leave ur underwear dried up with the sp*rm.Will the sp*rm be dead once it's dried up?Will it be safe to put the underwear in the washing machine with everyone'should clothes?

What if sperm was to drop on a bar of soap (any type) will the sperm be stop working if a woman was to use the soap down there?

If sperm was to fall on the floor or any where will the sperm stop working or dried up and stop working?
Ex:Bathtub Ex:Toilet seat

Let's say u were doing it in the Bathtub and the things got on the bath tub floor. Will water be able to wash all of the things that was down there. AND leave no harm toward getting a girl pregnant if she were to sit down on the bath tub?

Please tell me more inforation about sp*rm

Please please answer me with mature ness. No rude comments.Yes I know I'm too young.But please, this is for my health and knowledge.So.I'll be more careful and not end up being a young father. And tell me if this is normal for me to think like this . Once again please be mature with me and no rude ness. THANK YOU
