Hello,
Speaking from personal experience, and from countless friend's complaints, I make the following observation.
When you first meet a women, and she is trying to become your one and only, she kisses you all the time, holds your hand, infrequently criticizes you, the sex is frequent, adventurous and crazy. It stays this way while the relationship progresses from casual dating towards what most women want, a committed, monogamous life together. This is when things typically get all screwed up...
Next thing you know going out to dinner, vacations, parties, socializing, shopping, the house, the yard and all of life's small trivialities become more and more time consuming and important. The man finds himself being critiqued and ignored. And then, before you realize it, that adventurous, experimental, continually horny girl you fell for ceases to exist.
This has happened with EVERY one of my buddies. When first dating they would be getting laid in the car, at the gym, blowjobs everywhere, anal sex, bondage, etc, etc, etc. 8 years later the woman, in most cases, "isn't into that anymore"
I am going through this myself, being the last of my friends to settle down (I'm not married). Most of my friends have accepted this but I will not. I just had a conversation with my girlfriend because for the past six months she thinks I will happily exist with sex twice a month and the occasional blowjob. I continually try, with voice messages, emails, dinners, etc to keep the spark alive. She is trying to convince me that nothing has changed. But, luckily, I have videos of what we USED to do. I watch them and wanted to show her but she refuses to watch. I just told her this morning, after coming home from a trip without her to another dissappointing, lackluster welcome home, that I will no longer make the effort to keep the spark alive. I told her that after months of working at trying to motivate her I feel lousy because she is always tired, has a headache or a stomach ache. I feel rejected and humiliated, and it is only natural that when another woman shows me that she finds me desirable, I will respond. Just as a note: I have not gained any weight, I work out and stay fit, I don't lay around the house watching tv, I keep life fun and active. I am a successful professional and we spend our time together doing a variety of interesting activities.
I think the problem is that some women use sex to get what they want out of a man financially. I have a child with my girlfriend, I bought her a house and a car, and pay for everything. Her lifestyle is completely reliant upon my finances. Now, she has become accustomed to the life that years ago was only a dream for her (vacation home, boat, cars, country clubs) I only want what we had in the bedroom, I have always been kinky, she used to love it. I refuse to change and told her if she thinks that now I will accept this boring routine sex life she is sadly mistaken. Even though she tells me I'm wrong, I can tell that she is no longer into having sex with me, but if she admits this, and thereby ends the relationship, she will no longer reap the financial rewards of being with me.
This dynamic is why most of the married men I know that were very sexually active before they were married now have a girl on the side, the wife is the domestic partner and "mommy", the fwb provides the erotic component of life. The wives in these married couples try to keep the man faithful through detective work, and let themselves fall apart physically while they spend their days shopping and lunching. The men know they can, with a little discretion, get away with it because wifey is more concerned with maintaining her lifestyle and doesn't mind if hubby doesn't have sex with her. Hell, I know a few married couples in their forties that sleep in separate beds, mom sleeps with the kids, dad in the spare room. No plans to divorce, no sex either, Pathetic!
RANT FINISHED!
(PS I know that sometimes (infrequently) the roles are reversed)
