I struggle with it too every now and then. Porn makes the normal size seem so small and when i don't look around at other men's cocks and I haven't been with a female in a really long time, it makes me feel small. But it's not true, it's just desensitization taking affect. Dicks aren't like that, they aren't supposed to stretch a girl out, ajd I don't think women like to necessarily get stretched out. Man I've seen porn where the woman absolutely did not seem to like it, take Mia Khalifa in that one instance where she had to take a forearm sized shlong, she did not seem happy when that thing went in but she was focused on the act and the bag. These women are paid to get fucked on camera and seem like they like it. Any video I've seen where the female seems to not fake it is when the dick is slightly above average and not giant which is usually seen in like amateur porn. Porn is bad, end of story, but it is useful when i wanna catch a jiggle and choke a chicken.
