Mine breaks all the time

I wonder if that has anything to do with all the 'wrong #' calls. Or those calls which say 'please hold for an important message from so-and-so attorney at law'. LOL

(occasionally Avanti polyurethane condoms when there's a latex allergy for the lady)

I also will use 2-3-4 condoms during the hour (or more if longer date). I also apply a small amount of lube inside the condom to help with the seal (lubricant gets rid of air bubbles, the major reason for tears, the same reason latex gloves have corn starch on the inside).

I have had precisely zero condoms break in 10+ years of doing this.

FWIW, I think fucking with a Trojan is like fucking with a sock on your dick.

I've been using Skyn condoms, and have not had a problem in the last year while using them. They feel AMAZING

This was prompted by the thread but deserves it's own message. There is a new type of condom made from a synthetic resin called AT10, the brand is pasante unique. They are becoming very popular everywhere but here. A provider on this site introduced me to them in the most charming way.
The advantages are IMO
Stronger and thinner than latex (70% thinner)
Adhere to the penis (doesnt come off)
Great, safe packaging
petroleum products won't break them down.

Cons
penis must be dry when you suit up
Must be able to read the label that says "penis this side" (tough for the alcohol impaired)
looks weird (like saran wrap)

I've used them a half dozen times and prefer them to anything. There are definitely those who will not like them though and you can't buy them in America (yet)

I don't own stock in the company. My motivation is to get more Americans using them so I can start buying them here. The review I linked to says they are fragile but that has not been my experience.

I find that the only time a condom breaks is when the condom does not fit properly. Or it is put on inncorrectly.

Make sure the condom is not too small. Every once in awhile I get a client who does not fit my condoms.(usually too wide or too long) I have some larger "backup" condoms in case of this. Most guys under estimate their size(like women who think they're fat when they're not) You don't have to be XL to not fit "average" condoms. I reccomend clients bring their own condoms even if I have some...so many different brands and styles....seriously!

Putting them on inncorrectly can cause a break. I usually put the condom on the client myself, but sometimes they beat me to it  A condom is meant to roll on, not pull on! Sometimes it doesn't go down far enough....don't grab the ring at the base and try to pull it on that way! If you need to readjust it then grab the middle with your whole hand and pull down. Pulling on the base by the ring weakens it and I find this is where most breaks happen, at the base!

Stay Safe!
