you have NO need to worry!!! it's good that you clean though. that helps eliminate other things such as germs and viruses, like the flu, cold and what not. (which there is NO NO NO way you could get pregnant from ANY of those scenerios)
lmao I know how you feel about having really stupid fears.
I have one too many EXTREMELY retarded fears.
I'm afraid to eat pretty much any kind of refridgerated food that's more than 3-5 days old.
SPECIALLY meat. lmao
And I get in trouble ALLLLL the time for letting food go to waste.
But I can't help myself. Like you said. lol
You can't get pregnant from what's going on in your house. lol
Once the sperm hits open air they generally die fairly quickly.
Women only have a %20 chance of getting pregnant even having unprotected sex, so your chances of getting pregnant like that are 0.
Try not to freak out, you'll be fine.
also just in general like if either of them sit on the couch im afraid to sit there or they touch things in the kitchen etc..
