My Boyfriend And I Both Tested Positive For Chlamydia And

my boyfriend and I both tested positive for chlamydia and have both had our course of antibiotics, my boyfriend needed an additional course so he is a little behind me as I've already been re-tested to confirm the antibiotics worked and have tested negative now.

We will still be using a condom for sex and blowjobs till he is retested.

My question is: is it safe for my boyfriend to perform oral sex on me? Since I have now tested negative.
