I dont wanna argue neither,i just wanna write stuff from every corners,to not be too much subjective...its just exchange opinions.
Well,some younger men like to fuck old ladies,likes to fuck fat girls more than skinny
girls because they r attractive for them more than flat girls,but its all about taste
also many will fuck anyone when ther are horny too much,pussy is pussy no difference
also for many women who are turn on-dick is dick for them - its just sex
If you were on topic about Rebecca you could read that they can choice with whom
will work so its not so random and she enjoyed a lot as she said and had worked like 2 years
as porn star not just because money but because she likes sex and because she could choiced with whom
she did it and she said why she was return so many times to make porn again and again.
You should know also that he fucks them for free when they call him in hotel room cuz they are bothered while waiting for shooting;)
And to whom women we dont pay,all men pay...we pay them drinks,diners etc
Of course i wouldnt like ,as you wouldnt like to watch your mother when she has sex with your father..who would like watch it ..but that dont change fact your mother has sex as every human on this world
(but do like ur stuff, and have imagination about it).
