If a woman ever says that she won't date a man with a small penis, ignore them saying this totally.
In the same way that any sensible woman would ignore any man saying that their butt or boobs were too small.
People can say all sorts of ridiculous nonsense. That doesn't mean to say that you should take any of their ridiculous codswallop seriously.
They won't know your erect penis size till they have sex with you.
When they find out what you can do with your tongue, your fingers, your hands as well as your penis, they will be magically addicted to you.
That's assuming you are competent at love making.
The size of your penis isn't a real issue at all. The competency of your love making is the real issue. Sort that out - it's not too challenging to be competent in bed - and no woman that you make love with will ever make issue about your penis size.
If she asks about your penis size, either ignore the question, say "It's big enough." Or say "You're wondering what it's like to make love with me? Already? We hardly know each other. But seeing as we've gotten onto this subject, from what women have told me, it's quite shocking how bad most men are in bed... (followed by a discussion on love making techniques)"
In the same way that size of a woman's posterior and breast aren't important compared to what she does in bed and how she does it.
