cold sore help

so I had a cold sore or a spot on my lip last week and I popped it and it wasn't sore. then it healed like a spot and it healed in a couple of days.

2 days ago I gave my boyfriend a blow job and then l now have more cold sores or spots near my lip which is painful to try and pop.

could this mean anything and could I have given my boyfriend a std????? please help
