Connor doesn't strike me as a particularly sexual person. Well, not in the way that he'd have given himself pleasure as a teenager. My personal headcanon is that he didn't start masturbating until he was well into his twenties. I'd adore you forever if you wrote something based around a slightly flustered and suddenly horny, but ultimately very satisfied Connor exploring how to pleasure himself. As in, he knows about sex and erections, but hasn't experienced pleasure in this way until now.
