condom fit help

So, I am 7 x 5". My Wife was at the doctor and talked to her about going off the pill, and just use comdoms. The doc said to just make sure they fit right. I have used both regular condoms & Magnums. Redular condoms, any brand are tight. when i start to get soft after, i can see that at the end where the roll of the condom is it is squeezing in my penis. It is not uncomfortable, just tight. The magnum seems to fit just right. A little snug, but not squeezing.


The question is do I stick with the regulars, or go with the magnums? The normals aren't really uncomfortable, but I am worried about breaking. The Magnums seem to feel better, but because they are not super tight, I am worried about it falling off.

So what do you guys think? Should I go reg or large? Will they regular ones break? Will the big ones slide off?
