A lot of men probably think little of exactly what causes their arousal and corresponding erections with any degree of specificity.
Everyone is turned on by something, and it happens enough that it isn’t really investigated further.
If you’d actually like to know a bit more about yourself and your own sexuality, it might be useful to go through a little bit of mental exercise to determine what causes your erections the most.
A lot of men are very visual when it comes to arousal.
The entire “sex sells” marketing tactic largely exists due to this fact, although the same is true of people in general.
There’s not a thing wrong with being turned on by how certain women may look, but it can actually grow to unhealthy levels.
For instance, if you’ve gotten into the habit of watching a lot of adult movies, it’s possible you’re conditioning yourself to only experience sexual arousal over the most extreme of visual aids.
To check how “well rounded” you are, you should try just thinking about sex and all of the things you like or have interest in within that realm.
There’s nothing wrong if it ends up doing little for you, but at least then you’ll know a bit more about yourself in the process.
