I don’t enjoy cum

Hi, 24 year old here. I’ve been in a relationship for 6 years, am the bottom, and I never have my boyfriend cum in my mouth, dislike him cumming on me, and just am pretty turned off by the sight of cum

I recognize this is abnormal as a queer dude, and would vastly prefer I enjoyed cum more. I know it makes my partner feel like I’m not as into him (I am! He’s a super hot twunk!) which hurts our sex life and makes him feel physically insecure

If anyone had tips or tricks or something it’d be much appreciated. Please just help me out, thanks!
