Both in online and and real life girls often say I'm handsome.
But I don't know how to reply.
If I say "oh, not really", they say "no, really!"，it's an awkward disagreement.
And when I say "thanks!", they will usually reply "you are welcome", and than that's it.
I feel like my perceived "handsomeness" by some girls is being wasted by the lack of something else.
