Personal Question

Don't know if any other woman has gone through this but I'm not going to lie......sometimes I get curious as to what my s/o is doing all the time when they are on there phone. I know I know curiosity killed the cat. Anyway, but has any other woman ever been flipping through their s/o phone and found out that they have been watching porn but never seem to want to do anything with you? I know it's a man thing but I'm extremely insecure about my body and when I found this out it made me feel even more unattractive and like my s/o doesn't find me attractive on that level. Maybe it's just my 35 week hormones talking but does anyone feel the same or have you????
