Theories on ED

...Question: I've noticed that with some women an erection is less likely or more difficult to achieve than with others.

Does "erectile dysfunction" depend on your partner in any way in your opinion?

It would be difficult if not impossible to achieve or maintain an erection with a female one does not find sexually appealing.

So-called performance anxiety can be another cause if we become highly concerned about our potential to satisfy her. For example, we may be concerned about premature ejaculation or that our erect penis size is too small, and this can lead to erectile dysfunction.
