Agree with pyros. 5 months? Still the honeymoon. Lots of WK/AFC mistakes in OP's estimations and rationalizations so far. You are bending over backwards to rationalize. Get back to us in 1.5 years. The subtext of your posts is that she is just as -impulsively- devoted to you as she has conducted herself -impulsively- in the past, and impulsivity is the biggest and reddest of big red flags.
Surely you aren't her first boyfriend, so between dating relationships, she has banged all these guys? I'm liberal on numbers, but that's too many for 25 IMO. 35? SURE, No problemo, but there is lots of life between 25 and 35. There is more going on here than just a healthy sex drive.
Demote to plate immediately, then see what shakes out over the coming year or so.
... and to the gynocrats with the "double standard" hypocrisy BS, an analogy:
Two hunters hunt under different scenarios. The first has an unlimited number of animals brought and staked in their front yard every day ten yards away, can shoot as many as they like and know they will never go hungry.
The other is sent out blindfolded into unfamiliar woods miles from home, and has to shoot by noise alone.
One day both hunters happen to kill ten animals, far, far more than they want or need, but that's just the way it panned out. One of these hunters is a reckless, impulsive glutton, the other got lucky and may starve next year or month.
The "double standard" between women and men and the ways they seek, obtain, and are judged for sex they have is a complete myth made up by a gynocratic marketing culture seeking to keep that female cash flow pouring in by telling women "you can have it all," and "anything you do is permitted as long as it's what you want in the moment... you DESERVE it." Anyone who actually believes in the "double standard" rationally as cohesive and logical is a double-digit IQ dupe, moron or leftist.
Only the top, top fraction of a % of men have anywhere near the sexual opportunities that the average woman has, and can be accurately held to a double standard.
An average woman knows she can lay in her bed, tap a few words on her tablet or phone, and have a near infinite number of men she finds sexually desirable come to her to give her sex... without leaving her bed.
The average and -above average- man knows that if he doesn't hunt, he doesn't eat, and has no clue as to which and how many of his hunts will be successful.
Don't buy into gynocratic/feminist horse****.
