help me

Elayne • I'm a messy gal
So my boyfriend & I had sex today twice and we used condoms like always but for some reason I'm really paranoid today about it. Even though I did see the cum in the condom, I over think and think about the cum coming out through the sides or anything. His condoms do fit but I still have that fear. Someone pls explain if it's possible even if his condom fits
