Your doctor....then everyone you have been sexually active with
Std's are exactly that .. Sexually transmitted diseases.. They can ONLY be transmitted and passed on by sexual contact. You catch std's by the enchanging of bodily fluids.. This could be genitalia contact, but also includes genatalia to mouth contact (oral sex).
Yes. But she still has to come in contact with the std. Sharing needles thru drug use is a good way to get one.
Gonorrhea is transmmited by sexual contact with another person already infected with the STD.
Contact the institution concerned
If you are 100% sure he has never had any sexual contact with anyone, that would include oral (sucking), then no neither of you can give the other an STD.
Well first off go get tested for an std, sounds like you got problems.
Not really, but if it has a STD or HIV she can contact the disease through oral sex.
Yes it will protect you from a STD.
...if he has an std...?
Yes. Assuming that they knew or should have known they had the STD before they had unprotected / unsafe sexual practices with you.
If she had an STD then yes if not no you should not
People with STDs should not have sex and should inform their partner of their disease.
