There are lots of variables: head size, how your girth is distributed through the shaft, base girth. If you are very wide at the base, the condom rolls back “uphill” and you get less coverage.Ideally, there should be just a slight amount of extra space within the condom so that your cock can slide in it as you stroke during sex but a very firm base ring grip so that the condom will not slip off and semen cannot leak out.
XLs were about perfect for awhile when I was 5.75 - 6.00 G. But PE also caused my head to widen and XLs got more difficult to put on, then became too tight on the shaft as well.
My girth averages 6.25 now and I use the TheyFit model at condomania.com
Their D21 is wider than an XL and good for length, but snug. The U22 is good for girth, I can slide some within it, but too long for me - they’re about 10 inches. Because my base is a little wider, those rolled inches of unused rubber make for a tight constriction ring at the bottom and this sometimes interferes with ejaculating. But I’m OK alternating between the two sizes and buy both. (They are not cheap.) I use the 22s when I have taken Viagra and the 21s when I have not.So far as I know, the “22” size is the widest condom made anywhere. Outgrow that, girthwise, and you are going to be in a “pinch.” If anybody knows of something wider, tell me.
Advocet8 I have found a condom called “my size” they come in mm size and you could order your own size, I think the widest I’ve seen so far is 65mm, but I think they do go bigger, I will try them out and see what they are like.
Havent seen many condoms that you could pick the size of. I only have the sample pack. I am around the same girth as you if you are around 6.25 ish.
Start 6.5 bpel 5.75 eg Current bpel 7.0 eg 6.75 (7.0eg base) Goal bpel 7.25 eg 7.0 mid shaft
