<human>: when we met two years ago, he was a wonderful lover - i felt really lucky to have ended up with someone who turned out to be so good in bed! he would always be very enthusiastic about foreplay, saying it aroused him to know i was enjoying myself, and regularly went down on me.

he hasn't engaged me in foreplay for a long time, if i ask for it he huffs and acts like it's a huge chore so i don't enjoy it anyway. he hasn't been down on me in literally months. as a result of this, penetrative sex - which lasts less than a minute usually, when it used to go on for ten-fifteen - hurts me a lot, both during and afterwards.

the answer to this isn't 'talk to him' because i have and he just gets annoyed and carries on the same way next time. i love him so much and it feels so shallow to be upset about bad sex but i am so frustrated and haven't had an orgasm, or even felt wanted or appreciated, in about six months. i asked if he would consider foreplay/going down on me for my 21st birthday and he said maybe but that he wouldn't agree to anything in advance.

so, reddit, is it petty and selfish to be upset about this? what would you do?
