ashamed to have sex?

So I just recently became sexually active a few months ago. I’m 19 and have sex with my boyfriend often (protected, of course. i’m on birth control and we use condoms for extra protection). I grew up Catholic and sometimes I find myself feeling guilty that I am sexually active even though I do believe that it is normal. I guess just my religion makes me feel like I am dirty or evil for enjoying sex. As long as it is protected and I value the person that I am doing it with, I have nothing to be ashamed of..... right? :( Sometimes it really gets me down. And it ruins the mood sometimes because I feel guilty for enjoying it so much. Ugh.
