It seems to me that when you've reached the stage of life where y'all's children are eligible for AARP, all y'all's grandchildren are married, and some of y'all's great-grandchildren have their own Web sites, you should find a term other than boyfriend for the guy with whom you're hooking up, hanging out, going steady, or whatever.
No matter what y'all's age is, you can call y'all's boyfriend, "boyfriend".
