The wait is perfecntly understandable. You both have to be sure before taking a non-reversable step.
Once mine was done (during the same six-month separation in which I vowed to piece my marriage back together again) it was a -significant- relief to my wife, and has permitted her to enjoy sex much more, without any nagging "what ifs...." For my part, I never want to wear a 'raincoat' again: it became our primary BC measure after our last son was (accidentally) conceived, and after a few years of that, I detested them.
In your case, I would strongly suggest your working with your husband to find intercourse positions (that you can sustain) that provide the highest level of frenulum stimulation for him, so that he doesn't lose his arousal state (I -think- that's what you said was happening). If you like, I can share a couple here, which also provide excellent G-spot stimulation, which is why I adopted them -- primarily for my wife's benefit.
