Bf not wanting to have sex TMI.

So it’s been a few weeks since we’ve done it and I know it’s not all about sex but I’ve been horny 😩. I’m tired of masturbating and just wanna feel my man 😂. He’s always making excuses like he’s tired, we’ll do it after he’s done playing his game, it’s hot, he’s not in the mood etc. In a way I just feel like he’s lost interest when it comes to my body. Our relationship is doing good though so idk maybe low sex drive? Anybody have advice? I was thinking of getting some toys but idk kinda scared lol.
