Sexual problems

Hi guys, first time in this so I'm sorry if what I'm about to write is inappropriate for here.

im 21 and with my boyfriend 2 years now. At the beginning, sex was regular and great! In the past year and particularly months, he's been suffering with premature ejaculation problems. Now they are quite bad, as in if he lasts literally 60 seconds it's almost a gift! Last night he came before he even had his boxers off. I'm not a shallow person and I reassure him all the time that I still adore him and am very attracted to him.

needless to say it's having a massive effect on his self esteem, confidence, manhood and ultimately, our relationship. I know he still loves me and finds me attractive, but he has stopped initiated anyting because he's 'scared of messing up' . I've tried to make it as relaxing as I can for him, telling him not to think about it, just enjoy the moment etc.

He's too embarrassed to speak to his doctor because he doesn't think people his age should have this problem. I've urged him to go and told him it's nothing to be ashamed of etc. But he's not comfortable going.

I love this guy so much and I know Dec isn't everything, but it's been going on far too long and it's creating a weird boundary between us that never existed, it's kind of ruining our intimacy and relationship slowly but surely. ​

Please help if you can relate or have any advice. Thank you
