Welcome to icliniq.com.
Yes, it sometimes happens this way. You get an erection and can do intercourse because you are (probably) excited at the prospect of having sexual interaction with this woman, who you seem to have good chemistry with. But, you also probably did not realize at that time that she is not the right sexual mate for you, though a great intellectual companion.
Although your body responded through erection and other bodily reactions, your mind remained cold and unresponsive because the sex appeal is missing or you just see her as an intellectual companion but not as a soulmate. This happens, and maybe a reason why there was very little sexual excitement during intercourse or upon touching her.
That way, your guess that one is compatible with only certain type(s) of women is valid. What does this lead to? At least two possibilities are there.
- You continue to be disinterested in sex with her, and within a short time, would move away from her (at least sexually).
- Alternatively, you might slowly get used to her physical appearances, moves, sexual body language, etc., and slowly start getting the excitement, and eventually start enjoying sex with her without regrets.
It depends on how you see the situation and how you mend yourself.
