I like to have a sealed box with me on a date...  one just never knows.  I'm just average size & of course, like something thin for best sensation.  Need to be locally available, since I just buy a box at a time.  IF it gets opened, I leave it & buy another sealed 3 pack.    
Your preferances for & against.  

It sounds like you buy a 3-pack, and if you use one, you discard the other two. If I'm understanding you correctly, why do you discard unused rubbers when they're individually wrapped?

Like something you put over your boat when a hurricane's coming.  When you say an FC "feels funny" do you mean it tickles, or there's something odd about it, or what?

Because a significant percentage of providers, myself included, prefer that they still be in the sealed box.   This provides greater assurance that the gentleman hasn't tampered with them.  Yes, yes.... I know I can check for that but it's easier (and less-time consuming) if they're simply still in the box.  

They have the best fit and feel for me. Others are too narrow. A bit of lube inside the condom increases sensation. They are polyisoprene and not natural latex, so latex irritation is not an issue. It seems that when I leave condom choice to the provider (especially if we haven't met before) the condoms she has will be either too tight or too big.

This is for gals where we don't have a established relationship yet.  And, Yes, it's because the box is a double seal.  Situations like a massage girl where we don't have established limits yet.  Or to break up the old "I need to run out for condoms" scam.  

especially for married guys that don't want the evidence laying around.  I'm single, so a different mindset for me.  I never would have thought of tampering.  So there are guys out there that WANT to pay child support?

You should just say rubber.

My favourite for sensation are definitely the LeloHex.  Closest thing to using nothing at all that I've felt, for both parties.  

When I bring a 3 pack, I leave whatever hasn't been used.  

They are the thinnest I've ever found, lots of sensation.  And polyurethane is stronger than latex, so therefore less likely to break.  However, now I'm curious and might try one of the skyn rubbers everyone's referring to.

Is the Trojan Bareskin Polyurethane condoms. They are slightly wider than the SKYN Large.  

Wow , this was my first trying a FC
But I gota say , I expected this to be more dificult to put in .
I actually did it for the girl who also never tried one before .

Does anyone know of any good feeling ones, besides Skyn, that are not latex, and offer larger size? I am allergic to latex, but having a hard time with larger members, even with their large style. I would like to find something that works for larger gentlemen, but also doesn't make me miserable. TIA
