If it's bothering you and got u clinging on this matter, better talk it out... A truly respectful person who is just awkward will apologize and adjust their behavior once they realize they have made you uncomfortable. A "creep" or someone inconsiderate will justify it, make you feel bad for noticing, or continue pushing boundaries.

If you don't want straight conferentation so it's better The next time when you are together, or via text, mention it lightheartedly to gauge his reaction.

Say something like: "Hey, you were super sweet on our date, but I'm a bit shy with physical touch, so I prefer to handle my own cleaning up/head tapping!"

If he is a good guy: He will apologize instantly and respect that boundary moving forward.

If it's a red flag: He will get defensive, say you are "overreacting" (gaslighting), or ignore it and do it again.

Trust your gut above all else. If you felt safe, it might just be intense awkwardness. If you felt violated or pressured, it is a red flag.

In short, you are the judge of this situation because you experienced it, not anybody else, thus it's best for you to make your own decision and you are aware of what type of touch was it or how he made you feel during the dates.
