Help!

So Me and my boyfriend were having sex and he was a virgin i took his virginity and I had been already with two other guys and this morning I had a irritation on my vaginal area and I look and it looks like small blisters/ bumps could they be herpes? And could I have gotten them from him because every time I’ve had sex with the other guys we always used condom and now with my boyfriend now we don’t use condoms
