honestly, the fact that she is with him kinda says a lot, when we read between the lines. she is likely (possibly) kinda frigid and or unintersted in sexual activity, or at least the robust kind of sexual activity that her banging body harkens from hearty virule males. that would be my guess, that maybe she is repulsed by sex in general, or prefers some tame/calm version this guy dishes out probably on a schedule, like once monthly on a sunday night after pizza and wine (or scrabble). i mean, you can look at him and tell he aint tearing the back out of it.
her reticence could be from daddy issues, or some other who knows what conglomeration of issues she has ammassed over the years.
but yeah that's my guess, that she not only is not attracted to regular virule makes but probably repulsed by them. there seems to be no other explanation for her choice.
She has claimed to be a survivor of sexual assault, to what extent she was assaulted is anyones guess but I wouldn't be surprised if she has had a few bad experiences in her life and likes this dude because he's a little doormat who she has on a leash. She could do so much better but evidently likes the comfort of having a little lapdog as a partner.
