So the reservoir water won't infect me?
it's the sex act that gives you std's, not where you have sex.
you had unprotected sex so you should follow up with proper testing at the proper times. you can get tested for chlamydia, trich and gonorrhea any time after 1 week post encounter. syphilis after 6 weeks. herpes, hiv and hepatitis after 3 months.
