Further, while the infections are common in women, most trich infections in
men are relatively transient.
In addition, urethral infections due to STIs
in men do not cause symptoms which come and go. The symptoms typically are present continuously and then, if anything progress.
On the other hand, when men begin to worry about the possibility of STIs, it is quite typical for them to notice normal sensations which are unnoticed when their attention is not focused on the possibility of STI.
