I have had unprotected sex with 4 girls, but they were all virgins...is it possible for me to have STD's?
yes it is possible, plus you can't be sure they were all virgins
Yes - anytime you have unprotected sex you are at risk of getting STD's. The more girls you have unprotected sex with, the greater your chances of catching STDs. There's a very good chance that at least one or more of the 4 girls you had sex with was not really a virgin. Do yourself a favor and wear protection next time! Besides, are you ready to be a daddy now?
