Are all girls in their 20s so immature?

I am in my late twenties and have only had a few girlfriends in my entire life. They all have lasted about 2 years each and have also all ended pretty much the same way. I am not a weak or affectionate man. I do not have a need to be touched or slobbered on constantly. Girls see this as me not finding them attractive. I will not have before I am married because I am not a dirtbag. But all of the aforementioned things were not the main reasons for the breakups that took place. All of these girls saw how my brothers took their girlfriends on very nice vacations and shared rooms etc. I find that to be extremely wrong as this is something that should only take place when a couple is married. Again, they thought it meant I didn't find them attractive. I also never spent the night at their homes for the same reasons. And finally, all of them became fed up that I had no drive to move out of my parents house anytime soon.
