LOL thanks but in the pics the brand is another brand (Condomi XXL) that I tried once, and although they were less expensive than Magnum XL's, they were in fact smaller and a bit painful.

Now I use Magnum XL's but its a bit worrying that two have broken in less than a week (say two out of 5 'sessions'). I think maybe its that because the condom doesnt roll all the way down (theres about an inch left at the base) that it gets stuck there and when I thrust it breaks out of the end because my penis is restricted by it not going all the way down.

However, we used some lube today and that was fine...maybe things are sorted. We'll find out soon enough :D

Thanks guys.
