Unsatisfied 😔

Okay so I’m just gonna jump right into it... me and my boyfriend have been together for over a year and a half now, I love him very much and our relationship is great for the most part. But our sex life... I finish maybe 1 out of 15 times if I’m lucky. He never lasts long and he also no longer really does much foreplay anymore. He just grabs lube and puts it in you know? It feel good but for like 5-8 mins tops unless I really work to not let him finish so fast. I don’t know what to do. I have a high sex drive and in my ideal world, we’d be having great sex again together every day. I don’t know if he just isn’t into me anymore but till past the one year mark we had been having pretty good sex almost everyday. He has a high sex drive too, he isn’t cheating on either. That isn’t what I’m worried about. I just feel so sexually frustrated and I’ve talked to him about it several times. Any advice?
