Is it normal to be thinking about agreeing to my gf having a lover?
So my girlfriend is unlike any other girl I've known. She is a very, very sexual person. We love each other very much, but I know that she is sexually frustrated with me. I'm the gentle, sensual, loving type and can't be what she wants, even though I try. I also suffer from premature ejaculation which I know is a big issue for her. The thing about her having a lover came about while we were watching porn. Basically the stereotype pornstar stud with a big dick that can last forever while being very dominant (She likes being dominated). While watching this she asked me in a jokey way if I would be ok with this pornstar fucking her like that. She was sounding me out and everytime we watched porn she would say the same thing but each time in a more serious way, also while getting me turned on. This over the period of weeks developed into her telling me how frustrated in bed she is, even though she excepts that I've tried really hard to be what she wants, we both now know I can't be. She wants a lover, but only if I'm o.k with it. I love her so much and want her to be 100% happy, so I'm thinking of saying yes.
So what do you think? IIN? Can it work?
