Sex Tips

Me & my boyfriend it’s been a month we been dating & we have did oral, backshots & missionary. I used to be very insecure about my body but with him I’m not at all. I wanna try cowgirl position but I honestly never did it before. I don’t know how to build the confidence TO do it. We spoke about it already he knows it would be my first time doing that position. He doesn’t pressure or is weird about but it is something I MYSELF wanna try. Any tips?
