Why can't a penis go all the way inside me?

Well you could have been kind of tight. Or maybe your vag isn’t that big. And yes even if just the head goes in that means you are no longer a virgin. And im sure after awhile your body will adjust.

if it went inside you (regardless of how far in it went) your no longer a virgin you may have not been ralaxed and tensed up making it hurt or maybe hes big in the future make sure you use lubricant and remember to stay protected as well, so use condoms or go on birth control

if you have just started having sex then it will take some time for your body to adjust to it’s size have no fear the more you do it the better it gets and the better it feels

well he could just have a super-ginormous penis, which i hear is kinda good, or you could be tight and guys like tht soo

If it hurt and he couldn’t go all the way inside you,you could try it again but when he gets inside you and it starts to hurt stop pushing further and either you or your friend rubb your clit to message it but don’t pull out.or you could use alottt of Lube.which helps alot. And the last idea I have for you is to get a viberator and go at your own pace with it.trust me.I told my girl friend to do so with a viberator.the next week we were at it with no pain. Hope it helps!

huge penis is not good. its more likely to hurt

the vaginal canal is only 5 inches so if its bigger it wont fit

becouse ur small jk
