You should re-evaluate the kinds of girls you're sleeping with. Real relationships are a part of real good sex. Random cross-country hookups? Not so much.
Good lovers make a girl scream, especially those who take the time to figure out what makes them tick. Being pumped like an airgun only accomplishes so much.
Please do not fall for this "jerking" fraud. Your organ size is not a problem. What you will probably do is pay some huge price for set of instructions that could leave your sex organ in a worse shape than it is in now. The male sex organ will not tolerate jerking and pulling and tugging and being treated roughly in general. This will break down cells alright, but these cells will remain broken down, and you will end up in a world of hurt. Do yourselves a favor, please click on the Forums tab at the top, go to the right side under "Ask A Doctor" Forums, scroll down to "Sexuality & Relationships", and click on that. There you will find postings similar to your size-issues or you can ask a real honest, caring doctor and receive top drawer answers.
I have heard of the site ,but never tried it. I really don't know if it will work,I would have to try it. My penis is just about the same size as your's. I feel you're pain brother. Everyone I'v been with tells me it's just average, well average has never gotten anybody anything. All those girls were full of it, because if they thought I was a nice size they would be screaming it out during intercourse.My advice to you is to find a girl with a very tight vagina , and stick with it. And dont let her have you're kids natural .My Ex was so loose after, when we would do it doggystyle I culd barely feel her, It sucked, But once again she told me, Oh! baby! you're ***** is just fine. WHATEVER! I know the truth, I'v been with plenty of women all over the country, And they all have the same look on their face when I pull it out,and I'm not stupid, I know what the face means, cuz I have seen it to many times. Yea brother, I hate to tell you, but they like them lean, mean, and extreme.If anybody does'nt agree, then please put me, in my place?
