I think my boyfriend has a sex toy

Beatrice
I think my boyfriend has a sex toy (like one of those fake vaginas) I saw something that looks like one, but he denied he has it. 
We don't have a lot of sex tbh because I have low sex drive due to depression and anxiety, so much so that I think I am pretty much asexual (I am not too interested in having sex tbh). 
I don't want to force myself to have sex but at the same time I feel bothered that he has a sex toys and what he does with it in our house. 
Please tell me I shouldn't stress? :(
