How to cope with lack of sex.

Hi everyone. I (23F) and my bf (24M) haven’t had sex for almost a month. This has happened in our relationship before but last time it went on for two months because he felt insecure about himself for a while (wasn’t triggered by anything, he just started feeling that way).

My bf is going through a lot of stress atm and whilst I understand that can be a factor in decrease in interest in sex, I also don’t understand. I’m autistic (just to note) and I struggle seeing other people’s perspectives sometimes: to me, when I’m stressed, I crave sex more. I mean it is a stress relief after all. But it seems like my bf is the opposite and I’m struggling with how to cope with it. His affection has also decreased a bit (not majorly but he doesn’t compliment me as much, isn’t as touchy etc).

We have moved house recently (the start of this month) and idk, I just feel like as a young couple who’s just moved in, he should be all over me. I’ve tried initiating but I get turned down every time.

We recently attended a wedding where I got all dressed up, did my makeup and made myself look really nice and I thought he’d be all over me but no. That night he went straight to sleep and obviously nothing has happened since. I’m starting to feel rejected which I told him and all his response really was was “I promise you I’m attracted to you, I’m just very stressed”.

Since we live together and both get home from work around the same time I haven’t had much “alone time” and I get very very stressed when I haven’t, yk, for a while. So I’m feeling really anxious, insecure and downright frustrated because of this. I can’t expect anything though or exactly get mad or upset about him saying no. – he told me the other day after I got a bit upset that me being upset was unfair. I just don’t know what to do. If this is how he handles stress.. well I’m not a fan.

How do I handle this?? I’m feeling very very upset and I know it’s probably dramatic but I am struggling to cope with the rejection (again I’m autistic) and decrease in affection too.

TLDR; me and my bf haven’t had sex for a while. It’s happened before and I’m questioning things. He says it’s stress but I feel rejected. What to do?
