if you stay with him you'll get used to his size but it will stretch you some.
Also, I don't know if this is linked some way, but although I turn 17 next month, I only hit puberty 3 months ago
Hi Cedonia, From a song by Beautiful South, there a line that goes, not every penny fits the slot, Yes perfaect 10.
So you need to slowly expand your slot.
I gave somebody an idea some time ago, if your a bit of an artist and good with your hands, you can make your own wax dildo, you make one that now fits, and weekly you have a nice tub of hot wax and dip it, and slowly you will expand with it by using it on a daily basis, or twice even, if you have the time, and slowly you will get used to the extra size, till your on par with you boy friend, but dont worry if you break up, you will get back to you old size.
Good Luck
even a tight shoe has to be stretched you are just getting started if he is going to be your future husband this is a good thing if not after so long he is going to open you up to his size and a smaller man will not be able to please you and dont let him put your legs far back over your head this can cause damage later in life so u control how far you want him to go in.
Unfortunately, and what they won't tell you in health class, is that not every male is a match for every female physically. This has happened to my boyfriend many times.
