I won't get into the whole debate about squirting since it is almost as contentious as circumcision, but despite so many people claiming it's so common and that with so many women claiming they can, my experiences have said otherwise.
Despite being a a common claim and sought out thing when we were in the lifestyle, I've only come across a single woman who boosted of the fact and actually delivered. Personally this never mattered to me since it was something I've never been into (and I do find a little off-putting) and always thought too much of a deal was being made on something that in it's absence can only serve to make women feel inadequate.
This was experienced first-hand by my wife, who has never been able to squirt, when more than once guys would ask her if she could only to express obvious lament when she told them no; including one who lost interest in playing with her after that. She admitted to me this made her feel guilty or inferior that she could not give these guys what they wanted.
So while I believe some women can routinely squirt and perhaps a certain number can train themselves to, my opinion is most women don't and cannot. Of those who cannot, they should never be made to feel bad because of it and men obsessed with squirting need to learn real life biology does not follow porn. It is no different then asking if men can get hard all the time, every time and making them feel abnormal if they deviate from those expectations.
