It's a common complanit; also really common for guys in that situation to project it on everyone else as if it's a forgone conclusion.
I've lived with my wife for 5 years and we've had no change to our sex lives.
I wasn't projecting anything, just having a conversation with a gentleman who's in a similar boat as me. As for your sex life that's awesome man good for you. But as for me, this is my second marriage and third long time relationship, (living together for over two years), and this one's going on 7 years whilst the first marriage ended after 3 years and I can honestly say that this little issue has happened in both of my marriages, but not in my first relationship. Some of us really do miss the crazy sex, and that's not to say the sex life is bad now at all; it's still good. I just miss how young, stupid, and free it was you know? Most married couple's sex lives do change over time, it's pretty normal.
We're on like 8 years and the only change is in frequency because of our daughter. Communication is key people. Tell them what you want and ask they do the same and everybody wins.
Dude I communicate like crazy seriously; I say literally whatever is on my mind, all the time, without fail. I've been told I'm a bit too blunt with most things, and sex is no different. Not to throw her under the bus, but my wife's overly conservative upbringing and hyper feminist mother, who really hated men due to several failed marriages, has majorly affected how she views alternate forms of sex. I don't wanna get into too much information territory, but I didn't convince her to let me eat her out the first time until we'd been dating for over six months, and her previous boyfriend of FIVE YEARS never once got to do it, (he's my best friend so trust me, he's not lying; he really tried to), and although she admits that she loves it she says it makes her feel like a slut for some reason when I do it.
My only point here is that the whole "just communicate" thing is not always so simple. I wish it was. And honestly ever since my daughter was born it just seems like some things barely ever happen anymore. It's not a big deal, my wife's an amazing woman and I don't need consistent head to be happy, but I was just saying that I do miss it and I honestly do believe that a lot of men notice the rate of blowjobs going down pretty severely after marriage. Not all men obviously, but I'd say it's fairly common. The truth is that some women just don't really dig doing it much but they do it before we're married to make us happy. In my wife's words, "I just used to do it so much because I knew you loved it. I just feel like I shouldn't have to anymore." What do I say to that ya know? I'll tell ya what I said to it. "That's alright honey, it's not that important." Whether I believe that or not, I don't really know. But I know I'm not gonna beg her to do something she doesn't wanna do.
