My wife absolutely LOVES rough, aggressive , almost animalistic sex with her boyfriend, whereas with me, it's more gentle love making between her and I.
That's not to say we don't enjoy a quick fuck here and there, because we do... But her and her boyfriend almost always go multiple rounds, and her and I always draw out the foreplay leading up to sex/making love, therefore, it's pretty rare for her and I to go more than one round. I usually make her cum multiple times BEFORE intercourse, and even though there's times I don't cum, I'm totally ok with it.
Her boyfriend gets way to excited at times, which leads to him blowing his load without her having an orgasm. Instead of getting discouraged, she'll just suck his dick to get him ready for round 2... Something she's never done for me (I guess that's their "special" thing). If and when I ever blow my load without making her cum, she has me either rub her clit with my hand or has me go down on her.
