They’re more expensive than prostitutes, their bodies aren’t what they used to be and their children walk in during sex.

These are just some of the disgustingly offensive reasons that a growing group of men have given for not wanting to date single mums, The Sun reported.

On a recent thread on the secret sharing app, Whisper, tried to explain the warped reasons they ruled out dating single mothers.

Here, Sun Online, meets some of the men who are breaking a taboo by refusing to date single mums.

Jonathan Cass, 52, has joined their ranks, having been single for three years, and now makes a point of swiping left on dating apps and rejecting women if there’s any mention of a little one at home.

“I don’t want to be second best,” he says.

“There’s a real trend in current parenting that the children always have to come first and women now seem to live for their kids” says Jonathan, who works in film and television and lives in Dunmow, Essex.

“I’m a really spontaneous person and love the idea of saying to my partner, ‘Come on, pack your bags, let’s go away for a couple of days’ but you can’t do that with kids. Everything has to be planned and organised beforehand.”

While he wouldn’t mind if a potential partner had grown-up children, provided they were no longer at home and doing their own thing, “young ones are definitely out”.

‘I’M FEELING SELFISH’

“I don’t want to be part of a family unit and splashing out on days out together. Single mums are too expensive,” Jonathon said. “I’m feeling selfish and not dating women with children is part of that.”

And he’s not alone.

One shocking blog called Everything Must Go, one of the posts is titled: “Don’t date single mothers — here is why.”

Reason number five is, “A woman who has given birth can’t ever have a body close to what she had before carrying a child. This is not saying that having a child isn’t worth it, but this is not about YOU having a child. That child is hers, not yours. Her body was changed by something that is of no benefit to you.”

But dating coach Richard La Ruina, author of The Natural: How to Effortlessly Attract the Women You Want warns that dismissing single mothers as potential partners is a risky decision.

“Finding love is hard enough as it so to narrow the pool even further is a mistake,” he says.

“Yes, dating a single mother adds an extra potential complication but it’s not a total deal breaker.”

‘I WON’T SPEND MY HARD EARNED MONEY ON THEM’

Paul Dakers feels very differently.

The 45-year-old logistics specialist from St Ives in Cambridgeshire has never been married and has been single for over a year.

“I would very much like to meet someone and have a family of my own but I really don’t want to date anyone with their own children,” he says.

“I dated a girl for a year and she had three children and she lived a couple of hours away. She would come and see me every two or three weeks and I kept saying, ‘I’ll come and see you, I promise’ but I never did. I never met her children and didn’t want to.

“She’d talk about them constantly and I’d nod and shake my head in the right places but I wasn’t really paying attention. It puts me off that they wouldn’t be mine.

“What would they call me? Paul? Dad? Oh no. It’s weird. If they’re not mine, I haven’t brought them up and I’m not mentally prepared to cope with that kind of responsibility.

“I might also feel reluctant to spend my hard-earned money on them.

“It is getting harder at my age now to meet women without kids and I know it narrows down the numbers but I’m trying to stay hopeful.”

Dan Mower is another good example.

He is 46 but still wants to settle down and have at least two children, which can be an issue for some single mothers who are wary of entering new relationships and having more children.

“They’ve been there, done that and don’t necessarily want more,” says Dan, a self-employed businessman from North London.

“After all, it hasn’t worked out once before so why should they risk having more children?”

Dan has dated a number of single mothers in the past but is now avoiding them altogether.

“I’ve not had great experiences dating single mums and don’t want go there again,” says Dan.

“One of my exes had a 12-year-old son and we’d been on-and-off for a few years. The last time we went out in February, we were trying to catch up in her bedroom — talking, being intimate — and her son just walked in on us.

Dan also dislikes coming second in a relationship. “A single mother will always prioritise her children over me,” he says. “I’ve been stood up a few times because the children are sick or the childcare has fallen through and I want someone who wants to put our relationship first.”
