It might help BOTH of you if you kinda broke up the ‘session’!
A straight 45 minute ‘banging’ might be somewhat tedious (for her). You might want to try reaching your 10 minute limit and then distracting yourself by becoming a Lurve God and going down on your girlfriend for 5 minutes/suck her toes/caress her breasts, kiss her tenderly/write the alphabet on her clit with your tongue/[insert many other options here].
You can then ‘bang away’ for another 10 minutes and then repeat the above.
This way you’ll last much longer and she won’t!
Both of you win!
Good luck dude!
