Short sex 😩

So I’ve recently got a new boyfriend and we’ve only been together for about a month and when we have sex it feels so good but it literally lasts for less than

5 minutes which is so frustrating!! I literally think my boyfriend just cums really quick in general. The foreplay lasts a lot longer than the actual sex, but because it’s less than 5 mins it doesn’t give me enough time to orgasm and even when he’s finished I’m still so horny but he just chucks us the towel and then it’s finished, For me, I don’t even know how to bring it up as we havent been together very long and his sex drive isn’t very high anyway so I don’t want to knock his confidence !! Any tips on how to bring it up to him? how to make him last longer? n how to increase his sex drive ?? Help a girl out 😩😩😩
