Haha, wow. Fellas, here's a lesson, and let me spin it for you quick. Wear a rubber. Just fucking do it. If your girl demands it or not, it's just common fucking practice. It's like holding the door open for your girl when you enter a restaurant. There are certain things you do to get laid, and being irrational and going around slipping your dick in twenty different women would wearing a rubber will get you fucked up with some type of disease. So wrap the fucker up. I don't see how it's so difficult to do. Do you want to die a slow and painful death? Well go ahead and fuck whoever you want with no condom.
As for the second half of this question, to cover the out of the question part for the future. I think that's ridiculous. If you do get married, and you do want children, then you better plan on not using a condom, or else you're pretty fucked. So I think the word future is far to vague to even remotely begin to describe the condom matter as it relates to marriage.
I don't see why you don't just wear a rubber every time. It's not difficult to use, is it a hassle sure, but is catching an STD a hassle? Maybe not for you, and your cock, but I happen to like my cock, and I plan on keeping it, and ensuring it stays as healthy as possible. Plus a girl can fuck up birth control, then you're both fucked, because not only do you have a new disease now you have a baby who also has your disease! Enjoy the medical bills pal!
