Every fetish or quirk that has become visible in the world has given rise to a whole new subgenre of adult movies. The actual number of subtypes increases as long as some new form is established with a particular audience following it. When you look at the sheer variety of porn movies available, you cannot help but gasp at the various niches that are catered to.

The old slogan, "There is something for everybody", takes on a whole new meaning when it comes to porn flicks. The succeeding run through of adult movie types is far from being exhaustive, but it provides a sweeping view of what you can expect the next time you browse through an online adult video store.

A variety of tastes and preferences are catered to by adult movies that concentrate on actors with a certain look.

There are many subtypes under this classification. Some of the more popular types include mature flicks which feature participants in their 40's to 60's, MILF porn which features older women in fantasy scenarios with younger men (MILF stands for mothers I'd like to f***), and teen pornography which features barely legal girls pretending to be involved in first-time sex.

Some films focus on certain body parts as objects of arousal, such as the breasts, the butt, body hair, and legs. The race theme has gained in popularity over time with people from clearly different regions indulging in the sexual act.

Another subgroup deals with fetishes or fixations with a certain act. There are a lot of subtypes within this group, particularly the bondage fetishes where one participant is humiliated, degraded, hit, spanked, and name-called and occasionally hurt for arousal. Sometimes rape is simulated in the more extreme types of videos.

Perhaps the largest subgroup for porn movies deals with same sex intercourse. Heterosexual intercourse is considered as a bland norm in this genre, so more spiced up pairings are created to cater to different tastes. This is just as is in the case of men with men or gay porn, which include bareback or condomless flicks, bear (hairy), and twink (young) flicks.

Women with women or lesbian genres offer a different appeal since they feature women of varied forms and sizes. To some extent, this means that traditional porn does not cater to those who are looking for something other than the super-good-looking woman actor.

Bisexual porn usually features two men having sex with one woman, and threesome porn is the exact opposite, with one man having sex with two women. Transsexual porn features sexual acts between participants who were born in one sex and were medically transitioned to another.

Reality porn is a popular subtype which features amateur or simulations of amateur sexual encounters. The names of the types under this classification are highly suggestive, such as exhibitionist, upskirt and downblouse, and voyeur porn.

With the emergence of the Internet and the webcam, reality porn has been growing in numbers and popularity. Reality porn is big money these days. It is no wonder then, that people are keen to make quick cash in this field of pornographic content.
