Okay Greg Rucka is on the record stating that he doesn't believe Frank Castle has sex even though in almost all the different Punisher series when an attractive women would make him an offer he would have sex. This goes all the way back to the Mike Baron days and continued in Garth Ennis Punisher MAX run and beyond. I get the whole Artemis Entreri argument for celibacy but it doesn't seem to mesh at all with his past and the fact Frank has been made younger now.
CA: Because connection is vulnerability, and if there's a vulnerability in him someone will exploit it.
GR: This is why [he has] no friends, no lovers, nothing. Axel and I had an early conversation about whether or not Frank had sex. And Axel [suggested] that Frank would maybe service the machine's needs, but my response was that he doesn't need to. He's really doesn't. There's a reason why you have wet dreams. And if he has a wet dream, he can just tell himself it was about Maria. But I do think it's a very delicate nerve ending he has developed, and he has to guard it very carefully.

So this begs the question should frank have sex with an attractive women if the oppurtunity presented itself? Or should he turn it down viewing it as a weakness?
