Grades 0 to 3:
I think most men, especially older ones, cannot have grade 4 erection every time. It is normal if occasionally you have grade 3 when you are with a naked woman. You can still enjoy the fucking. If you have a skillful prostitute you can get a grade 4 erection quite easily.
A few days ago I was at a function. A woman came and sat in the row in front of me. She was quite sexy and was wearing a dress that exposed her shoulders and arms. Also, tantalizingly visible were her red bra straps. My cock was soon in grade 1 status. As I ogled at the sexy bra straps against her tempting flesh, the hardness grew to grade 2 with a little cum oozing out. If I were in a room with her and she started to strip, my hardness would become grade 3 and if she touched my cock, my hardness would rise to grade 4.
I think many men experience impotence once in a while. Sometimes the reason is psychological. If he finds something very sexually-arousing in a woman, I think he can get an erection quite easily.
Even a penis between grade 2 and 3 can enter the vagina. In this case you hold the penis at the base to make it harder and then push it into the vagina. You can continue holding it and move it forward and backward in the vagina until it gets harder and can move on its own. Or you can continue holding it and fuck until you ejaculate. In this case your pleasure will not be as great as that of a hard penis.
Some men use cock rings to increase the strength of their hardness. A cock ring is a ring that can be placed around a man's penis, usually at the base, primarily to slow the flow of blood from the erect penile tissue, thus maintaining an erection for a much longer period of time. There are many types of cock rings. I have never used any ring before so I do not know if they are effective.
