It typically takes my girlfriend an hour or two to climax, and it's making me less interested in sex with her. I listen to instructions — I do all of the elaborate simultaneous twisting, pulling, sucking, and rubbing to help get her there, but after an hour of that with no end in sight I'm discouraged and frustrated. I got her a vibrator to help, and it still takes so long. I've never had this issue before and it's tripping me up.
Something I can't get out of my mind is I asked her how long it usually takes when masturbating. She said while watching porn, three minutes.
It's gotten to the point that I've turned down sex or pretended like I was too tired because I just don't have it in me to perform for that long.
We're also pretty kink friendly, but it's starting to feel like her interest in that is just a crutch from being totally desensitized to normal sex. Like she always needs the maximum amount of stimulation to get off.
I think what she does alone is none of my business but at this point I think it's affecting the relationship.
Does this sound like porn addiction and is there any coming back from this? How do I even talk to her about this?
