How does a stud have sex with their girlfriend?

🎀Sam🎀
I have wanted to know the answer to this for the longest but too afraid to ask any studs that i know lol. How do they have sex with their gfs?? If a stud wants to be seen as a male they wouldnt trib with their gfs then would they?? Do they use strap ons and pretend to be a man? Im really curious
