I had protected sex a week ago, but received oral sex unprotected. What are these bumps on the glans

Should i be concerned with these bumps? are these herpes they appeared 2 days after my sexual encounter.![image]

Probably just a pimple/irritation. Just keep an eye on it for a few days, but should resolve.
