(NSFW) What is the best way to handle this delicate situation?

How would you broach this delicate issue with a man? We’ve only started seeing each other recently and have slept together on a couple of occasions, both of which were dreadful. It was over before it began. Initially, I didn’t think much but when it happened again, I wondered if he might be struggling with premature ejaculation.
The other thing is, he doesn’t participate much in the way of foreplay. I care about this guy so don’t want to hurt his feelings but it’s very important to me to have my sexual needs met too. I suggested next time we take things slowly, get to know what one another like/dislike, etc.
He doesn’t have much relationship experience.
Both times I’ve come away feeling really pissed off and dissatisfied as he has made no effort to pleasure me. I want to nip this in the bud early without hurting his pride.
Any advice would be much appreciated.
