<human>: Condense the text into a few key points

So she sent me a few pictures where she'd drawn a dick pointing to my mouth...the same kind of thing as you see around Reddit for one reason or another sometimes.  My response to the first one was, "Ummm why?", and she continued sending them.  Apparently she thought it was a cute thing couples do.  Now, I think a really clever dick drawing could be funny, but this wasn't even clever.  So I didn't really respond.

Now she's upset that I didn't think it was funny/respond in kind, and then she got upset that I didn't tell her to stop sending them if I didn't like them.  I just thought it was kind of weird and juvenile, but wasn't going to make anything of it.  Am I crazy for being kind of annoyed at the whole situation, and is this a thing other couples actually do?
<bot>: She sent me pictures of myself with dicks drawn on them.  I thought it was juvenile and ignored them.  She got upset because she thought it was a cute coupley thing to do.  Is it?
