1.A couple questions actually

You need to be 18+ to post you stupid faggot

Don't know what the fuck you are on about with canal imprints.

Me and gf have sex once or twice a day and only thing thats noticable is that she gets looser but after a day of not having sex it returns to normal. All the crap about vagina's staying loose is complete bullshit (except those huge fucking dildo things I believe that)

Jesus fuck, what country are you from because the sex ed/health class needs to be completely redone.

All of this.

A god dam child comes out of it and sometimes heals tighter. Your dick ain't gonna change shit.

The average girl hates massive cocks. It's painful and they don't enjoy it. If you aren't shit at sex an average dick is more then enough.
