I agree with him to an extent, going down on someone is a submissive act (whether you are a guy or a girl)
You're knowingly doing something that is not enjoyable (putting your mouth where disgusting bodily fluids come out of) to give pleasure to someone else. You're knowingly suffering to give pleasure, which is submissive; and obviously men shouldn't be submissive.
However if you go down on a girl and can constantly give her mind blowing orgasms, SHE WILL NEVER LEAVE YOU and she'll be obsessed with you
There is not one correct statement in this post.
1. It is not necessarily submissive. In fact in certain situations (eg tease/ deny) it can even become a dominant act.
2. It is not suffering, rather quite enjoyable, for many people of either sex.
3. Men can be submissive, if they want to.
4. Giving a girl mind blowing orgasms is never a guarantee she will be obsessed with you, and never leave. There is nothing that will provide such a guarantee.
Need to do a little more research my friend.
