Natural erection enhancers fall into a few categories in the market of natural and herbal male enhancement formulas:

1.) Formulas specifically geared toward longevity in bed and premature ejaculation prevention

2.) Formulas geared toward simply enhancing your erection for more a more pleasurable orgasm. This usually involves making your erection harder and longer lasting in the process, since often slightly longer lovemaking sessions result in much more powerful climaxes.

3.) Enhancing the length of your erection during sexual excitement, and throughout the entire process of sexual intercourse. By default, this usually also enhances your climactic experience, as well as enhances your length, width and girth by filling the penile chambers responsible for the male erection with more blood, which automatically creates more sensation.

What drugs fall into the category of natural erection enhancement?

Specifically, there is not one male sexual dysfunction drug that outright claims to actually enhance the size of your erection, but they often do increase the size of the erection, and enhance the sexual experience due to forced, increased blood flow to the penis, resulting in longer lasting erections and more satisfying experiences in the bedroom.

Herbal formulas often have the same effect in this way.
