Well I'm not a wife, but I thoroughly enjoy making out with a sexy lady.
I did get together with a couple that asked for no kissing, and it ended up feeling very awkward for me. It was the first time I had experienced that and made it a bit difficult to stay in the mood at times.
Nothing against their choice, and I completely respect those who prefer no kissing. But it would most likely be a deal breaker for me at this point.
