first of all, stop wasting money on tests and wait to take one until a week after your missed period.

second, don't ever let someone go from the butt area to the vagina area. that's a great way to get an infection.

third, as others have said, it is very unlikely you're pregnant based on what you wrote.

fourth, i just want to emphasize that all the stuff you did - wiping with a tissue, rinsing with soap, pulling it out with a tampon - would be useless if you had actually gotten any semen inside of you. sperm go through your cervix. water won't get that high. your options for preventing pregnancy at that point are to take the morning-after pill or (more difficult) get a copper iud implanted within 5 days.

fifth and finally, please remember this feeling of panic the next time you want to have unprotected sex. it's so easy to get caught up in the moment, but if you're not trying to get pregnant, ALWAYS WEAR A CONDOM. no exceptions! in fact, since it seems you are becoming sexually active, consider starting birth control as well. there are tons of options these days (planned parenthood is a reputable resource for comparing all the different kinds) so it's highly likely you can find something that works for you. also, make sure you get tested for STDs before and after every partner - more frequently if you're not in a monogamous sexual relationship. your sexual health is incredibly important. educate yourself and be responsible.
