Do women do this intentionally?

It has happened me a lot, but why do women sometimes put their boobs against my back/shoulders, or sometimes when Iโ€™m sitting down and they touch my hair they put their lower belly against my shoulder. Donโ€™t they feel it? Is it intentional? Cause whenever I feel my dick bulge is on the way I immediately move, cause Im really conscious about it. But I really donโ€™t know about women

(It has happened to me with normal female friends and females friends that kinda flirt with me too)

Helppp jajaja
