He Doesn't Last Long😩

I have been getting really close with this guy (now my boyfriend as of last night) and things got kind of heated and I ended up giving him a handy. I didn't want to go all the way, and I wasn't even comfortable doing oral yet, but I gave him a completely dry handjob for maybe 5 minutes max and he came. I don't know if I have some kind of super power or if he's just really sensitive, but I thought I was hurting him by accident rather than pleasuring him😅 has anyone else experienced this?
