For starters, my girlfriend loves these. To me, it's a condom. She can actually feel the tingling sensation of the cooling. I can't really feel the warmth. That might actually be a good thing, as the idea of warmth is a bit... unnerving for some men.

It's a condom and it works; the design is the Trojan ecstasy shape, which has proven to be a favorite of ours.

When I opened the packaging, I noticed that these were larger than "normal" condoms, but realized that is due to the shape. The smell of the lube is... a bit overwhelming at first. Put it on and stick it in!
We did run into the issue of it sliding, so I had to be careful and stop occasionally to readjust. The lube stays on the man after discarded, so pt has to be wiped off. Luckily, it's a water based lube so it comes off fairly easily. If you are throwing the used condom away, just know that all the lube will make it stick to anything, so use a trash bag (voice of experience).

As it is a latex condom, be mindful of allergies.

Also, as the effects will be different on different people, so be very careful when first using. Communicate with your partner everything you are feeling. I have a few friends who hate it because they're more sensitive, and it burns them. Not in my case, but a warning nonetheless.

The effects didn't kick in automatically either, so taking time with this is highly recommended. A quickie won't utilize the potential of this condom. If you take it slow, she'll thank you for it because of feeling the tingle. Also, DEFINITELY not a first time having sex condom. Just throwing that out there.

As a side note, Trojan is really the only brand I trust. They are the top tier condom for a reason; they are effective and can spice up the bedroom. Enjoy!
