STD ?

So Firstly I don’t have any symptom, I think I´m fine, just want to make sure.

I´ve never had sex without a condom, but oral yes.

My first partner was virgin, but not the second one. (It was before that I was with my currently bf)

Can I have any std during unprotected oral/bj ?

I will be on the pill so I want to be sure to not have any before having sex without condom. (Of course I will make sure my bf has any too)
