Actor Aftab Shivdasani has been part of quite a few sex comedies and his upcoming, third instalment of "Kyaa Kool Hai Hum", is also from the same genre. However, he does not like being tagged as a "specialist" of the genre because he feels Riteish Deshmukh is more worthy of the title. Aftab, who worked with Riteish in sex comedies "Masti" and "Grand Masti", just announced the launch of "Kyaa Kool Hai Hum 3". When asked if he has become an expert in doing sex comedies, he replied humorously: "Riteish is a legend (of sex comedies....) He is a sex guru and we are still getting there". Riteish also featured in the first two parts of adult comedy "Kyaa Kool Hai Hum" and "Kyaa Super Kool Hain Hum". Aftab replaces Riteish in the third instalment of "Kyaa Kool Hai Hum" and said: "'Masti' and 'Kyaa Kool Hai Hum' were always the adult comedies and ironically, Riteish was a part of both. Tusshar was part of 'Kyaa Kool Hai Hum' and I was part of 'Masti'. To be produced by Ekta Kapoor's Balaji Motion Pictures', the third instalment also features Krushna Abhishek.
