I think he is curious... What do you think?

So he is a close family friend. His mom has been best friends with my mom since they were 18 years old. I remember growing up with him and always hanging out. We almost look at each other as cousins. Anyways i thought he was curious from a while back. I must have been 12 and he was 10. He came to my house for like easter or something. Our parent were downstairs hanging out and we were up stairs in the room playing video games. We started wrestling and i had him in a head lock he grabbed my penis so i would let him go. It shocked me but i didn't say anything. We wrestled again and he kept doing it. Later it turned into every time i would go to his house we would always end up wrestling and something gay would happen. One time he pinned me down in missionary position and said "you're gone take this D today" of coarse it was in a joking manner but i honestly think if the opportunity comes up he would take advantage of it. Finally the last reason that i think he is curious is because last yeah i came out to my closest friends. Im bisexual. He was the first guy i told. He said he was ok with it and he didn't care. Then he asked me if i had and experiences. He wanted me to go into detail about them. It was a little weird but i didn't mind sharing so i told him. He would say ewww but then say he wanted me to keep going. I told my best very best friend who is a straight guy and he accepted me but he never asked me to go into detail about anything especially not sexual experiences. So i talked to him last night and he was jokingly saying that his GF went down on him and decided that she wanted to toss his salad.. She really didn't but it caught my attentions. So then i said that it feels really good.. and he asked me to go into more detail about how it felt. IDk but i think he's curious. He gets undressed in front of me all the time flaunting his huge penis and trying to smack me with it. idk if he will get offended if i ask.. What do you think?? Do you think he's curious? He is very masculine has a girlfriend and has sex with all these girls but if he is considering guys, i want to be the first one.. is that wrong?
