I'm a size queen, but I must admit, some of those guys would be too big for me to take, even with lubrication, all at once.
Now, if he were the type of guy who was patient, kind, considerate, and understood my Anatomy & Physiology, without being selfish, then we could work something out. Let's just say, I take the head, day 1; 1/8 of his cock, day 2; 1/3 day three. Rest.
The next day, 1/4 of his cock, day 4; 1/2 of his cock, day 5...etc.
A real man who has been around the block a couple of times -- will understand that not all women are loosey goosey, your average women is not a porn star.
Nevertheless, any woman who can take these cocks, let me know your secrets -- perhaps, I'm missing something! LOL.
