Boyfriend’s Assfro

So a lot of men have coarse hair on just their lower back which is referred to as, often times, an ‘assfro’. Personally, I just discovered my boyfriend has some and it’s kind of a turn off for me. We’re probably going to have sex soon and I kind of want him to get rid of it before then. Is there any nice way to put it or do I just need to suck it up? (I understand that if he asked me to shave a part of my body, I might take offense to. I really just don’t like that ONE thing).
