LONG FINGER NAILS

im
My boyfriend has really long finger nails & sometimes theres stuff that gets stuck underneath them. We don't live together, but we communicate alot through skype. I'll bring up the fact that his nails are longer than mines, but it doesnt seem to bother him much. I really dont like them, i think it could interfear with when we have sex. So the question is: Does this say anything about his hygiene?
