TL; DR----> Woman is vegan, doesn't mind I ain't one. She's allergic to latex and I can't do any non-latex except animal-membrane. Can I use this type without informing us first? Vegan non-latex condoms break easily as well. We are both clean.

Hear me out. She's not allergic or anything and I'm the one who be wearing them.

I'll bring my own.

Usually, vegans don't mind everyone around them not being vegan, right? She knows I ain't one.

The issue is that she's allergic to latex. I am thick in the middle but like a pencil at the tip, average base. The only one that fits being Regular Magnum. It's (tapered down) taper-style, so, it fits although it's large but doesn't feel like one because it's tapered.

Also animal-membrane condom. That's it.

Non-latex ones are not stretchy or tapered. They also break easily.So, a medium one would make me go limp after a few minutes while the large one would fall off right there and then.

Both of us are clean.
