During a stay in a hotel, I masturbated and ejaculated in my underpants. I left my underwear in the sink under running hot water for about three minutes. (The running water was directed at my underwear in general and most probably not at the semen spot on my underwear, so I don't think the semen was completely rinsed off). I then soaked my underwear for about eight hours overnight in hot water initially, which as time passed, turned into cold water. At that time, I made myself a cup of instant noodles and accidentally spilled some of the soup which contained MSG (monosodium glutamate) and salt into the sink of water. There was a yellowish stain on my underwear and on the sink as a result of this.



The next morning, to my horror, the cleaning woman removed my underwear from the sink and drained the water.



My concern is:



1) If she touched the spot on my underwear where the semen was and then touched her vagina, will she get pregnant from the leftover sperm? I am really scared that the lady might shower after that and touched her vagina or insert her finger (with live sperm) into her vagina and get pregnant.



2) What if she rubbed my underwear with semen on against her vulva, will there be sperm to impregnate her? (Something like sperm stealing.)



3) And do you think all traces of sperm will get rinsed away during that three minutes of rinsing or the sperm cells will stubbornly get woven into the fabric of my underwear and get into the water during soaking? I am really disturbed that someone other than my wife would have been in contact with my sperm, which is something very personal.



4) Is it true that semen (sperm) stays alive in moist environments like in a pool of water? Does the spilled MSG and salt help keep the sperm alive?
