Okay so I've been seeing this guy for sometime and we've been having sex like almost everyday lasting sometimes half an hour to 2 hours and he did it inside me the last days of my period until the very first day it ended and the days after that we would have sex and he would just get up like he already finished but always tell me that he couldn't. I have not seen him finish outside since he always tell me that he almost but couldn't. I could feel him get really hard then he would suddenly be quiet, breathing deep, he would stop and I could feel his thing return to normal and continue and get harder again. I always ask him if he did it inside but never admit it, I am worried because we're not using any protection at the moment. I couldn't tell if he actually finished inside me because I heard women would usually be "dripping" afterwards but I haven't. I asked him several times why can't you c*m but he keeps saying "almost" and that he is trying to be "potent". The other day I saw bubbly liquid came out when I peed after having sex with him, it's like saliva but thicker in volume and smells of bleach/chlorine.
