Every time I start to get aroused and fool around with my bf, I lose interest really quickly. It's like I have to be super horny in order to have sex. Otherwise, I just start and then I'm like naaahh. And of course my bf gets really upset, which obviously doesn't help things. Any suggestions for how to stay interested? Oh. and I know it's an option to power through, but I've had bad experiences in the past, so I don't want to have sex when I'm not in the mood because it might make me lose interest altogether and bring up bad memories.
