My last LTR was with a chick who was a straight up freaky slut. No gag reflex, loved sucking D, loved cum, loved anal, face fucking, rimjobs, honestly anything I wanted she was down. Started dating this 21 year old for about a month and I think I have the IRL version of porn decinitization. Shes hot but the sex is vanilla af and theres times I honestly cant even get my dick hard. She was on her period the other day and I was super horny so I told her to go down on me and she did for like.... 45 seconds and stopped, fucking stopped. Then this morning I was down for some morning sex and asked her to go down and this chick had the nerve to tell me "I mean we can have sex" like bitch, that is part of sex. I just said fuck it and took a shower because that insta-killed the boner. I'm at a loss for what to do or say about it.
