<human>: Give me a shortened version of the text

Before I begin..I just want to note that this is a very sensitive subject right now as I am taking it quite personally. Please be direct but sensitive with comments.

I (26F) have been with my BF (35M) for about a month now. We started having sex about 1.5/2 weeks into dating and have had sex about 3 times.. All of which I think was pretty good for both of us. In the past week and a half or so though he doesn't seem interested in initiating it. I have even tried to get something going by rubbing his chest, kissing his neck, etc and he doesn't bite. I know that these things are common in relationships but I feel like it is way too early on to hit a lull like this. I'm wondering how I should address it or if I should give it more time. There are a few outlying issues that I've also tried to consider so as to not drive myself crazy.. 

1. He has had several injuries on his knees and they have really been bothering him lately. 
2. He wakes up really early for work and as soon as we lay down for bed he passes out- like legit falls asleep so there isn't much time to get something going. 
3. Last time we tried neither of us had a condom- usually he does but I think he ran out..not sure if he hasn't bought more and just doesn't wanna start without being able to finish? TMI- we've finished in other ways that don't require a condom- so doesn't seem like a good reason.

I just need some suggestions on how to approach it. I'm racking my brain thinking it's something I've done. However, everything in our relationship is on the right page. He's very affectionate- random kisses, cuddles all the time, terms of endearment. So I feel like he's still very interested but I can't help but think he's not sexually attracted to me anymore.

I'm open to trying things but at the same time I'm very nervous of being rejected especially if I put myself way out there. Please help. The Reddit community has been so helpful in the past! Thanks!
<bot>: my boyfriend of a month doesn't initiate or seem interested in sex lately. What can I do or how can I approach it? I feel very insecure because of it. Thanks'
