It depends on the reason for the boner and if there is going to be a release any time soon.
1)If there's a partner and we are working to a finish, there will be no ache.
2)If I'm masturbating and going to finish, I can edge for a few hours... no ache, just a pleasurable throb.
3)If there is a tease that may not lead to a finish.... might be aching within minutes. Example - got into a "relationship" a few years ago where we couldn't ever get together privately. One night after having dinner, a few drinks, and some long goodbye kissing and groping... I was throbbing and aching the entire 25 minute drive home. If the roads hadn't been snow covered, I might have relieved

myself while driving.
It was an extremely explosive finish when I did get home.
