Congratulations, it's not marraige that does your sex life, it's kids.
The thing that people never mention, is that getting married gets you into a secret club of sorts. You gain a lot of respect from so many people, your wife to be will probably notice it on a greater scale.
It's a bit like what happened to me at Jewsons;
'paying cash mate?'
'Nah, account number given'
'Oh, hope your project goes well Sir. If you need anything else here's my card, just give me a call and I'll have it delivered to you'
