Hi KellyC,
As so many other pointed out if you have to slam the frunk to close it, something is wrong. Maybe the latch is bent or simply out of adjustment. But geeez, there is never a need to slam it.
This was a common problem with the original VW beetle. The latch was a flimsy thing and took only one slam to mess it up. But when all was well you could close it easily with one hand and slight pressure.
On the Boxster, when everything is correct it takes minimal pressure on the lid right above the latch to close it. Get it fixed yourself or let someone else do it for you. There is a slim chance if you go the wrong way with adjusting, you'll fix it so you can't open it
Good luck with it and no one thinks you are an idiot for asking. The only foolish question is the one you don't ask.
Cheers
