That is ONE horny otter there I tell ya's! I find it cute though that the artist who I presume is the female otter is open about her sexual needs. Never really liked or understood the stereotype that a sexually hungry male is a stud but a sexually hungry female is a slut. Although I ponder if it's possible to have one individual satisfy her needs; she seems to swing the door both ways. ;)
Still, I find a woman that knows what she wants and asks for it tends to have a better fulfilled sexual life for both partners. <3
Generally the whole slut/stud thing is because, and I quote, "It's harder for guys to actually get sex from women but it is easy for a woman to make herself fully available to guys."
That being said, the reverse is also possible, it's just harder to find.
Edit: Also, to note, I like to think of studs (male or female) as people who put in effort to get sex, while sluts are the people that just open their legs/part their cheeks and are willing to be fucked by anyone. Definitely think the "Doing the fucking" vs "Being fucked" is generally how people compare the difference between the two.
