My boyfriend and I got sexual yesterday after a swim at like 6 PM. He rubbed his member around in the crotch area of my swimsuit bottoms (I wasn't wearing them) and probably got some sperm residue from a previous ejaculation and maybe some precum. The next day around 9 AM I went swimming. Is there any way that any sperm from his foreskin and his preejaculate could survive in a room-temperature bathing suit? The pool is chlorinated, btw.
