opinions please!

this is going to sound dumb but i get nervous over very stupid things sometimes. me & my s/o have sex (i’m on birth control) and we use a condom every time and he pulls out. sometimes (like twice ever) after he took the condom off i think he only touched the outside of it and then a little while after he fingered me and i get nervous he could’ve had cum on his hand because i don’t think he did, plus i’m on birth control. is that stupid to worry about?
