Hello I have read a lot about groinal responses, on Wikipedia it says that groinal response can cause orgasm because primitive thalamus takes thoughts just as sex not sex with particular person. But it also state that groinal response is anxiety and attention to genitals that causes Blood flow to them and physical arousal. Some of articles I have read also confirm that anxiety, selective attention and monitoring arousal in one's genitalia can increase physical signs of sexual arousal.
So can physical arousal cause also unwanted orgasm? I have read tons of topic were People state that it is easier for them to reach orgasm while having groinal response which is physical arousal.
