My girlfriend likes to give me oral sex, is she good for marriage?

Um... I don't think that should be your only criterion for marrying her....

She's probably great for marriage.
You on the other hand...

I have no idea.... Answer these questions Do you work well as a team? Do you believe the same things morally? What annoys you about her? Can you deal with that for the rest of your life? How is she with children? How does she treat her family? Do you have the same goals in life? Are you honest with her? Is she honest with you? Can you both trust each other? Do you both have the other's back? Are you there for each other when life gets flipped upside down? How does she handle difficult times? How do you handle difficult times? Do you both see eye to eye financially? Do you know how to communicate open and honestly and respect the other's honesty? Do you respect her honesty even if it's not what you want to hear? Does she respect your honesty even if it is not what she wants to hear? Do you genuinely love her and care for her? There are these questions and many more that I can't think of.

As you can see there is a lot more to consider in marrying someone than for good oral sex.
If you are not sure about most of these then get to know the answers to these questions. Marriage is living a life together, not just having sex together.

Sex and oral sex are just a couple of things people do. Marriage is a lot more than that. Caps90 has a great reply.

How are those two things related mate.

Caps90 is the reply to go with!

Yes. My girlfriend and I both oral sex each other to cum. It good all the time so I give her marriage. Last time oral sex each other she not make my nut go boom so divorce. Be careful out there my friend, ladies...are...of course only there for head and nothing else.
I really hate when she's there to comfort me and what-not. Just need head...uhhhghh.

swallow then marry her

Just because she likes giving you oral sex, it doesn't mean she is marrying material. She may be so addicted to it that she may give it to other guys also, and maybe not maybe she may remain faithful to you... Marrying someone these days is just like gambling, sometimes you get a hand that looks like a winner that loses and cost you and sometimes you get a winning hand. It depends on how much you love each other and if you both are willing to work on the relationship... And the list goes on.......

Eu. That's disgusting. You want to marry that filthy slut? How could you? Your mamma would be so disappointed....
