I've dated 9s and I guess you can say 10s, even though I hate that number, but basically goes for girls that you just can't point out a flaw or something you'd like to change.. so maybe 9.5 is more accurate, but regardless, I've dated some smoking hot chicks..
YES, you do get bored after a "while", could be a few months, but definitely after a year mark you are a little "bored"... doesn't mean that you can't do it, but it's just not the same urge..
One explanation here is that we guy like VARIETY. I think this trait is more common for men, and even males of different animals. For example, they actually did an experiment where they tie up something around the eyes of a bull, and make certain that he CANNOT SEE at all, and put him in a huge area with a bunch of different cows. Now here is the amazing part, they had some wires hooked up to the bull that measure how excited he is ( I know, weird lol), and everytime he had sex with a NEW cow, he was the MOST excited. When he had sex with the same cow again, he was not as excited! Remember, the bull CAN NOT SEE!! And he is STILL not as excited when he is having sex again with the same cow.
This shows us that we simply like novelty, and after a while are just simply not as excited as we used to be in the beginning.
Second thing I’d like to mention is something I’ve heard from one of my uncles. This man was quite the ladies man when he was younger. Just a pure natural, who just KNEW how to deal with women. Even today, he has a hot wife, he still can make a room full of women bust out laughing from his jokes. I mean, he is one confident and funny son of a gun. Well, one time he told my brother and I about “getting bored” with sex with the same lady. He said “as soon as you have sex with the same girl for 1000 times, you will not be as excited anymore. I don’t care how hot she is, once you get over that 999 number and have sex with her for the 1000 time, it just won’t be the same anymore and you’re not all that crazy about it as you used to be.” Now, I think this number is just a number that someone pulled out of their anus, but the analogy is good. Pretty much, there is a certain number of times you can have sex with someone before it is just not as exciting.
Now, I don’t want any happily married guys out there to take this the wrong way and say how “it can’t be just the looks, it’s gotta be more, bla bla”, sure, true, I agree you should have some chemistry with your lady, but this doesn’t prevent that “loss of novelty” from kicking in. I’m not saying you stop having sex with her either, actually, quite the opposite. I tell everyone to KEEP having sex, no matter how bored you are or “not in the mood”. SEX PREVENTS MOST OF YOUR PROBLEMS. So even though it’s not as exciting as it used to be, make sure you keep doing it and doing it well. Concentrate on pleasing your lady. I’ve never heard of a satisfied girl running around or breaking up with a guy because “it’s not you it’s me”,,,, lol oh no.. you won’t hear anything from girls who are getting piped down lol. As one of my old friends used to say, “no matter how long you’ve been with her, you have to keep laying the pipe”.
So, to OP, yes, this is pretty normal. But if you do like this girl and want to keep her, well you just have to keep doing what you have to do. I think you know what you have to do
