i don’t know what to do (TW-SA)

so i (18f) live with my two housemates (28m and 28f) and recently my male housemate has repeatedly made sexual comments about me/ my body, joked about asking for ‘favours’ for money, gives explicit ‘compliments’ about my body. i’m aware that because i’m over 18 it’s not technically ‘illegal’ but it’s unwanted, makes me uncomfortable and is in my own home. i don’t have proof of it so i don’t think i would be taken seriously if i went to the police and it’s making me not want to leave my room.

is there anything i can do?
