Hi, I'm 16 And I Have Questions About Condoms. I'm

Hi, I'm 16 and I have questions about condoms. I'm usually quite bashful but this is a serious concern for me. My erect penis varies from 7.5 inches to 8, my girth is 5.5-5.7inches. I tried a medium condom but it felt too small, I tried a large but it felt too tight. If I were to move to an XL condom due to my girth would it make it less safe due to it not being as tight as a large?
