No, it's good to hear you vent - I've been having some similar thoughts myself (i.e., should I become a nun or what?)
To reassure ourselves, I think this must happen to teenage boys all the time - surely we're not the worst cases out there?
As far as increased arousal at the start of a new relationship goes, feel no guilt, many of us have been there... Must be mother nature's way of getting us pregnant back in the day
On my end, another mixed day - some tingling, some dull throbbing (of the sort you get after you've pulled a tendon or something). I've found that some touching actually decreases the tingling, probably for the same reason that rubbing a stubbed toe decreases the sensation - but I keep the hands away nevertheless!
In any case, like you, I'm mainly worried about persistence / getting worse - but we'll see!! Hang in there!!
