Am I asexual?

So I was in a long term relationship for about 3 years. Our sex life was okay but I had trouble enjoying it. I rarely felt turned on, and a lot of times it hurt. I enjoyed giving him head because I liked making him happy. I used to really like masturbating once in awhile but I don’t even do that anymore. I’m on antidepressants which I think affect my libido. I haven’t had sex in almost a year now and it’s really rare that I miss it. I’m not sure if i genuinely don’t have much interest in sex or if it’s just because of my social awkwardness/strict religious upbringing which I think taught me to avoid all things related to sex from an early age
