Well make a doctors appointment to get tested, just in case. Also, you should ask to get a pap smear done since you are sexually active. Though it may be something simple where he was being rough and made you bleed. Don't stress out over it until you can know what is going on.
Could just be he popped ur "cherry" just because u had sex before doesn't mean he popped it then
Was this the first time you had sex?
And it's safer to NOT trust that they're being honest with you. Sorry bout that.
Irritation/infection is the only thing I can think of. (other than what had already been suggested) I would strongly suggest you be tested (you'll probably have a pap done as well since you're sexually active) and I also strongly suggest you never engage in unprotected sex. Never take someone's word that they're clean. Your own health is at risk and it's safer to trust your personal health on the hope they're being honest. They don't really have an incentive or reason to be truthful when it comes down to it.
no, i have never been tested, now im really scared.
i've only ever been with one guy. he had two other partners.
im only 15 and it would be really humiliating to have a STD or whatever.
is there any other possible things it could be.
and thank you for helping.
There are many many possibilities for what the bleeding could have been... STD, STI, irritation, cut/scrape, etc. Have you been tested for STDs?
