Honestly, YES there is such a thing as too small and I have seen it with my own eyes. I am talking about the size of half a womens pinky, in length and width! I felt extremely sorry for the poor guy. I knew him through my stepbrother at the time (parents no longer together). And yes, he was one of those guys who bragged all day long about how much sex he had, how good he was, how he banged some girl ALL night long and she was just screaming the entire time. When I saw the truth for myself, I almost laughed, but didnt because I realized his over confident, arrogant, ******* attitude was likely because of extreme self esteem problems. Like, literally, his penis could probably be considered deformed because it was so so small for a grown man, and it didnt really get that hard either (but he came, he was just more of a shower, than a grower). There is like, no way he could get it inside any woman ever.
If you want a totally honest opinion from a woman about your cock, you can message me a photo of yours. But, if you are just looking for reassurance, it sounds like you know yours isnt small lol.
ETA some women really do love big cocks and a little pain during sex, but there is a limit to when they are just grotesque and not useful, but thats like, way out there. Luckily I havnt seen that in person!
