You have to remember this in Issei's point of view because Kiba can get the same amount of girls as Issei or even more just on his looks alone the reason why Issei attracts them is his Sacred Gear being related to Dragons because of the aura that it exhudes.

I have nothing personal against Issei but if Kiba was actually serious in trying to attract girls he would have a horde of them remember by his looks and personality alone guarantees success all the time.
