I think heterosexual anal intercourse is the most common mode of transmission in females.
And the second most common mode for both males & females would be IV Needles (drug abusers).

a) heterosexual anal

It is because heterosexuals are more common than homosexuals.

Keeping the mode of transmission the same i.e. anal, heterosexuals should win!

Anal intercourse is more common in heterosexuals, because heterosexuals are more common than homosexuals...you r right...

Correct Answer correct answer

IF WE SEE MOST COMMON MODE OF INTERCOURSE HERE ITS VAGINAL NOT ANAL...

so ANSWER is HETEROSEXUAL VAGINAL

second most common is HETEROSEXUAL ANAL..
