I've been thinking if that's a bad sign or normal: when I'm fapping, I almost never imagine my girlfriend. I prefer to fantasize about my exes, friends (mostly 3 attractive girls) or watch porn. During the weekend/when we meet, we have sex like usual. Does it mean that she doesn't excite me?
Sometimes I also imagine someone else while having sex w/ her. It helps me coom harder and faster. Is that bad? 🙄
