Heather Corinna, the founder of ScarletTeen, a Web site that discusses "sex education for the real world," said younger men have "less awareness and control" over ejaculation.
"And if we're being really forthright, we also can safely say [withdrawal] is probably the most-sabotaged method by male partners," Corinna told Salon.com.
"In other words, it's the one male partners will most often agree to, then not comply with, either by talking a female partner into just letting them ejaculate, or by saying they did so on accident when it wasn't at all accidental," she said.
But Jones suggested it wasn't fair to say that men can't be counted on to act responsibly.
"Most interesting is the response that many men can't be trusted in the heat of the moment," she said. "Sometimes it seems men can't win for losing when it comes to sexual and reproductive health. We argue that contraceptive is a couples' issue, that women should not be solely responsible, yet we don't think men can handle the responsibility."
Megan Carpentier, who wrote the Jezebel blog, "Can We Stop Shaming Women Who Practice Withdrawal Now?" argued that although the method may not work for every couple, her reader reaction illustrates the "real lack of knowledge" women have about their bodies.
"We are told only that every 28 days you bleed and you could be fertile at any time," she said. "It's a scare tactic."
"Every method requires knowledge and responsibility," said Carpentier. "Most women aren't given enough information and are scared of their bodies."
The Guttmacher report, she said, lifted the stigma that surrounded a couple's choice to use withdrawal.
"There aren't only three methods to have responsible sex," said Carpentier.
One of her readers, EvieB agreed.
Unemployed without insurance, she said she'd had "horrible experiences" with hormones and condoms.
"The withdrawal method has worked very well for me, and I'm glad to see that there is research being done to show that it's not as ineffective as people might think," said EvieB. "And maybe now I won't be seen as completely responsible for using it."
