Bf doesn’t want to have sex with me

So I’ve been with my bf a couple of months now and we don’t have sex a lot compared to my past relationships where we used to have sex AT LEAST twice every time we saw each other. He says that he doesn’t have a very high sex drive and that I shouldn’t take it personally but I’m finding it very hard not to take it personally. He simply says he just doesn’t want to have sex with me but it’s not my fault.

I don’t know what to think and I feel really insecure about myself now.
