Most guys we deal with say they use condoms but when it gets to where the rubber meets the road, there is no rubber. They show up without them or try to sneak the dick in without one on. One of our regulars always tried to slip it in and would say "I only want to put in the tip". As if the tip couldn't possibly be the disease containing end.
I try to be practical. Condoms can definitely ruin the spontaneity. We have had several guys lose the erection as soon as the condom goes on. Even after saying they wear one the break in the action seems to cause problems. A common response is "this never happens to me" or "I'm not used to wearing a condom".
My impression is guys want to get her so hot and bothered that she forgets about condoms and any other pesky rule that might exist. And sure enough that does happen sometimes. I carry condoms with me anytime we play and have them ready so the "I forgot to bring a condom" excuse doesn't work. So in the heat of the action a common phrase directed towards me is "dear, could you get a condom?".
My rule on condoms is like any other rules. If my wife doesn't follow the rules, I smile and remind her later but never, ever get mad or critical. If my lovely wife gets so sexually excited that she jumps on the guy and shoves his dick in her pussy bareback, I don't say anything. I want her to have a great time and that means sometimes she might just go for it.
When it comes to condoms the variety pack isn't for people like us or it would contain different SIZES too. 🙂
