I say "no." Yet, I sometimes see videos labeled something like "wife with bull filmed by husband" and the guy/bull has a small to average sized cock. Now, I guess small and average guys will say that they can fuck a woman as well or perhaps better than a well-endowed man based upon technique. I supposed that could be true if the well-endowed guy can't stay hard or has poor control. But, otherwise if things are relatively equal I don't see where a wife who is used to a good sized penis is going to equally enjoy to the same degree a guy who is smaller.
On the other hand, if the wife is married to a guy who is average to small, she definitely can enjoy way more the experience of a significantly bigger cock than her husband's.
The feedback I have heard, in general, has been the bigger than average penis makes the sex much more intense for the woman although some will say it doesn't necessarily make her orgasm feel better but again just the fucking is more intense. Certainly the novelty of someone different can make the experience more exciting but again I don't see how a small penis sized guy is truly a "Bull."
