Guilty about the past?

Hey! So pretty much I overthink everything. But once and a while I start overthinking things I have done before my current boyfriend (of 2 years). I feel bad for being with previous relationships intimately. When I was young I sent nudes even though I wasn’t comfortable. My face wasn’t exposed but it still scares me that one day they will come back. Does anyone else ever worry about this kind of stuff or feel guilty about it?
