Hi, I'm 22 (M) and I was recently watching a youtube channel that posts comedically narration over episodes of an 90's sitcom set in an american high school. When watching these videos I found myself attracted to one of the girls who I thought was 18 years old or over. Majority of shows and films I've seen have actors that play characters that are a lot younger than their real age, for example: Marty Mcfly is a 17 year old but Michael J fox was 25 when playing him. In Derry Girls they're aged around 15/16 but the actresses are in their late 20's. So naturally I assumed this actress was 18 or over and was convinced she looked old enough. I looked up the actress and found a video on youtube of a compilation of attactive/revealing photos from modeling and photoshoots etc. I masturbated to the video which contain a mixture of photos from her late teens, 20's and 30's and possibly 40's. After this I began to doubt and worry if she was actually 18, the Show ran from 1989-1993 and the actress is 46 meaning she was 15-19 during the series her characters wiki page said she was 22. There was a certain photo that I found attractive were she was wearing a jacket and bra which she easily lookes 18 and the way she was dressed it would be very immoral if she was under 18. I found date for the photo and it was from 1989 so she was 15, this caused me to worry even more because that is so wrong and I feel ashamed with myself. I keep worrying and my ocd is getting worse and worse. I feel I shouldn't beat myself up over it as she's now old enough to be my mother and the photo was from way before I was even born. I've seen people commenting on the same photos of her saying she's hot and that she was their childhood crush - many people stating she was a well know childhood crush ofthe 90's. However I can't look past the fact that in one of the photos she is 15 and I feel like a criminal and keep hating on myself. If I knew she was 15 I would totaly steer clear and tell myself I shouldn't be attracted but I had no doubt at that time she was 18 or over and didn't think about exact dates. Should I really keep beating myself over a photo over 30 years old? I just really beed some advice and support on how to overcome this and wether I should be worrying and wether I'm still a decent person and not some monster. My main worry is that I acted on this thought and masturbated to the video, and like when I have had counseling they say a thought is just a though unless you act on it, but my main thought was 'she's attractive and she looks over 18 and older actors always play younger characters so there's no redflags here' so I thought my actions were fine - until I find shewas 15 and completely freak out. I did wonder that of to show the picture to guys my age they too would say theywere attractive like a lot of people have already done on the internet. l do think its wrong that people would dress up and take photos of a 15 year old in those kind of clothes and I know I'm not attracted to girls that age I even only look to date girls right around my age (20-23). I keep thinking about and worrying what people would think of me and wether i can even have a normal life without having all this guilt and shame. I just really need some advice on how to deal with all of this. Am I overreacting and worrying too much or am I a bad person and deserve to feel this way? Just going crazy with worrying and anxiety at the moment even though it happened about 3 days ago. Can hardly get on with my life because I keep fixating about what I did.
