I am really good at companionship but I lack experience in sex. To put a short story together, during my stay at my uncles house his chocolate lab would do things to me like bite my nipples, lick my genitals whenever she got the chance then she would sit down and lick herself a lot. I am aware that all she was doing was just exploring my body to some extent and had nothing to do sexually but she did get me to question what I knew about sexual communication . I am aware of flagging, and I have read on other websites that females will rub their backside on you. My questions are, are there more ways female dogs can actively show their interest in sex? What would those signs be? How would I go about showing a female dog I am Interested?
