I agree with
@DarkSithLord47 on saying fuck no to Diane.
I think the way they got her portrayed, she probably does have to get checked often. Hell, the clinic staff most likely knows her by name

.
She's probably had the clap so many times, that even a large audience studio with an applause sign lit, couldn't compete

.
Maybe had so many treatment needles, that it puts the Betty Ford clinic to shame trying to help heroin addicts...Lol
Although, would give credence to the fact that she can't take birth control pills, as it would mess with the treatment she's having to take.....would also be a good reason why she has her heart rate the way it is, not because of running everyday but because of the chemicals of her treatments

.
I think I've heard, the worlds most interesting man say " I don't fuck her often, but when I do....I use Trojan's extra thick, and double down on the dick".
Hell even Indiana Jones has nicknamed her "Needle Dick" , because after you use her, you have to get several needles in your dick...Lol
He was heard saying that she is indeed a temple....The Temple of Gloom.
I'm beginning to suspect that, she probably has a hidden POV camera in that hair of hers. Where some dudes put notches on the bed post, she keeps POV videos of fuck buddies....Lol
Sorry for the rant guys, I just think they shouldn't have done her like that, mostly if they are making her as a cover plan or a potential Love Interest.
It definitely turned me off of her quick, just as the slut that rooms with Sandra (Lisa I think), I cant seem to find an attraction to her, now that I stupidly witnessed her getting plowed by the old, ugly, fat ass,that normally wouldn't be able to have action with a 100 dollar hooker, unless he offered 200.
I still like the game though, just wished for some alteration to side chicks. As Haley is the main dame, she's always my first priority, so I guess the rest is trivial (with the exception of some medicated dick shot now)...Lol!...……………..Peace!!
