Kama Sutra Master

Kama Sutra Master is a perk in Fallout 2.

Effects
You can have sex and unlock all dialogue option with any sex-specific characters regardless of your stats and you gain +2 points in the porn audition at the Golden Globes.

Calculation
The Chosen One's sex rating is measured by primary statistics and optional perks, traits, and reputation titles such as Sex Appeal, Kama Sutra Master, Sexpert, and Gigolo. A calculation of the player character's current stats takes place every time they have sex.

$$\frac{(CH * 50 + EN * 25 + AG * 13 + ST * 12)}{100}+(\star)\ge{9}$$

The formula named "obj_sex_rating" in the game files produces a number 1 through 15, the numbers rounding up and down. The higher the number, the more favorable the outcome. Ratings include great (9) required for porn star or gigolo reputation title, good (7), normal (5), bad (3), and horrible (2). The star is the formula is for sex perks, the following of which grant these bonuses to the formula check, including +2 with Kama Sutra Master, +2 if a Sexpert, and +1 with Sex Appeal.
