Does anyone else get crushes?

So I thought I was aroace cause I didn't feel romantic or sexual attraction towards anyone but, however I sometimes have 'crushes' but it's not like I want to have a relationship with them or have sex with them or anything, but still it's like I find them attractive for some reason and I get nervous and it's confusing. Also I have celebrity crushes but I don't know if it has something to do with it
