Aroused by talking about sex life

Same here (again . I felt this too and was bothered with it, especially when I’m talking with other guys. Then, they confirmed they feel the same kind of arousing. We concluded that it must be a normal body reaction like salivation when talking about food. Only in this case you are not going to “eat” afterward necessarily
So, I think it's perfectly normal, just ignore it when it happens (knowing that most of the others feel that too.) And if that really bothers you then try to avoid sex themes in conversations. There were other situations when we misinterpret signals and situations as sexual and get aroused.
There is truth in this,

just think about why would you talk with someone else about sex. In most cases, it’s boasting and trying to leave an impression … but there can be other reasons, like having sexual problems, asking for support, confirmation, etc.

 

I don’t get this personally but during a reboot (or atleast ever since I’ve been engaging in NoFap), I’m constantly looking for information regarding sexuality, porn and the issues with it. A lot of the time it does bring my anxiety but never arousal, but I’ve always wondered if this is a coping mechanism when I’ve left porn behind for me only to discover information, articles and stats regarding sexuality, the practices and all the negatives (health effects, exploitation, trafficking, normalisation etc). I do this when I feel like watching P and when I’m not even feeling up to it. It’s weird because even though I’ve learnt some much about the issues of sex, I’ve developed anxiety. Maybe it’s a nature of morbid curiosity, but I’m now trying my best to stop and focus on real life problems.

 

I think it is perfectly normal to feel anxiety while reading information about the reality of porn. But I don’t think @Cognac had that In mind, I'd say that he thought on explicit sex talk with lots of descriptions
