My current boyfriend and I have been together almost 4 months now and he is amazing and the sex.. well it lasts maybe a minute and doesn’t feel too good. I don’t get turned on by him anymore and have to imagine having sex with this other guy I used to hook up with. Ive tried showing my current boyfriend what feels good and tell him things that don’t but he just can’t last at all and is too impatient with foreplay no matter how many times I ask for more. Help
