I'd like my partner to make more effort with his grooming and personal hygiene. He never uses moisturiser, doesn't wear aftershave or even floss his teeth. The worst thing though is that he doesn't wash under his foreskin.
We did discuss this once and he told me that it is tight and uncomfortable to pull back. I suggested he went to the doctor's but he said "it's fine, I'm too old to bother doing anything about it now".
He takes offence very easily and gets very stroppy if he thinks I'm criticizing him, so I haven't brought it up again, but our sex life is almost non-existent these days, and this is a contributing factor. I feel he can't be bothered to make an effort for me, and tbh I don't really fancy him due to this.
How can I approach again (he doesn't take hints)?
