Follow up to my earlier post. HUGE TW FOR POCD 21+

So I made a post earlier today regarding POCD specifically about people in their mid/late teens (See attached picture of earlier post before continuing reading). I ended up confessing this to my girlfriend as usual. This isn’t the first time I’ve confessed fears/thoughts about some teenagers being attractive to her. I’m showed her the picture that I was worrying about, and she said that she thought the actress in the picture was good looking/hot as well. She has said similar things when I’ve showed her other pictures that I’m worried about being attracted to, and I know she’s just trying to comfort me but it’s worrying at the same time. I’m afraid that we’re both ephebophiles or something :( When I talked about how I feel disgusting and creepy for thinking these things sometimes, she said “Well I’ve thought the same things. Do you think I’m creepy or a pedophile?”. She is of the belief that even if I do find these girls attractive, that isn’t necessarily wrong because it’s not like I would ever try to communicate with them or date somebody that young. She also believes that a lot of the people I’ve had these worries about look older than their ages due to makeup/style (I tend to show her the pictures that trigger me, which I know is bad). I’m worried that this is an excuse. I don’t want my POCD to latch onto her and make me fear that she’s an ephebophile. I love her more than anything and I’m sick with worry and questioning both of our morals. I feel like it would hurt her feelings if she knew that I was having these fears about her (and my own) character. And now I’m going back and recalling every related event, every time I ever watched p*rn in the “teen” category, every time my girlfriend has comforted me over these thoughts, etc. I’m really not doing ok today. I’m leaving for a concert in like 15 minutes and idk how I’m going to stay present with all of this fear and doubt. I feel so alone, and like an absolute monster. I’m sorry for venting so much, I just don’t know where else to turn. I could really use some support.
