Sadly it depends on the girl. I wish being large was universally liked.
The last girl I was with had already given birth before and she was still incredibly tight, I was amazed. But it still comes down to what the girl likes/was told to like (same thing). In my experience the sluttier they are, the more like they big dicks. Pun intended on that one. Also consider how much she was sexually abused in early or teen years. That seems to play a part too. Put these factors together and you can usually guess right the first time what a woman likes. Haven't been wrong yet.
>>1, don't bother with any enlargment methods. Only surgery works but it gives you a small boost and repays you with partial loss of function. All interwebz ads are fake. Imagine that.
