well i had sex with my boyfriend several times we use protection all the time except for sometimes during oral pleasure he has been my first and only sexual partner
but he has had sex with one other partner before me a 2 year ago and has used protection . he says he received oral pleasure from the previous patner but never has givin it back besides me
my question is
is their any reason to alarm my self? (even thou i tested negative after we have been together more than year)
