I have recently realized that i am most strongly attracted to women that look similar to how my mother looked when she was my (their) age. I have always been attracted to girls that looked liked that, but found out about the connection after seeing my mom's photos from her twenties,
Am i fucked up? Is this normal?
Completely, 100% normal. This is basically the most normal thing there is. Taken both several psych courses as well as a Human Services course in Human Sexuality, and done a lot of extra reading on these subjects.
People don't talk about it because people are immature little shits.
Since you were attracted to that type of girl before seeing your mother's young pictures, it is unlikely that there is anything Oedipal going on.
But some experts say that, just as we are attracted to people who have interests and personalities like ours, we may be attracted to people who resemble us physically, and what you may be seeing in the girls is a bit of yourself that you happened to inherit from your mother. (You look like mother, girl looks like you, so girl looks like mother)
