OP - please show the below to your partner:
I'm 14 weeks PP. had an easy vaginal birth with no instruments, no drugs and minimal tearing (one small graze, one small tear- 2 stitches in total)
I still haven't had sex since with DP. This is because I'm BFing and feel a bit touched out, am a good stone over my usual weight, smell like milk, haven't shaved my legs for 16 weeks, my hair is falling out and haven't slept more than 3 hours in a row for about a year.
None of these things are about the tightness of my vagina. They would be the same regardless of C Section/ vaginal birth. They are about me being a new mum and adjusting to my new mum bod. And feeling a bit frumpy.
Yet.... My DP still fancies me. He still touches me- and stops when I ask him because I feel "touched out" by the baby. He's told me he's up for it- and he's told me he knows why I'm not right now. And he tells me he thinks I'm a rockstar for bringing our baby into the world, and caring for him so completely.
And that's how real men operate.
Yes. I did piss myself after my birth. At least 4 times in the first few weeks- every time because I was laughing SO hard at something DP / baby had done.
I hope you can make your girlfriend laugh that hard too, in the midst of those crazy, long, scary, lovely first weeks.
I also shat myself, projectile vomited and howled like a wolf while I brought our baby into the world. Because having a baby isn't like picking up a pizza. You have to actually do some work to get them here.
No idea how baggy, tight or otherwise my fanny is yet. But I know DP won't give two shits when he goes in to find out. Because I'm not a hole for him to put his dick in. I'm his girlfriend, the mother of his child, and - crucially- a human being worthy of respect and dignity.
Grow the fuck up- or do your girlfriend a favour and leave her. Buy a fleshlight and wank yourself silly, you tosspot.
