@Loalora,
The responses to this thread show a real aggressive prudishness. Several responses are directly attacking the original poster. I don't see reason of then a general aversion to sexuality.
The original poster...
1) Is inexperienced and is asking for advice (this is good).
2) Is in a committed relationship (also good).
3) Watches sexual videos (nothing wrong with that).
4) Cares about his partners feelings... and asks her what she wants. (very good).
5) Has his own desires which he is expressing responsibly. He is being clear to her about what he wants (good).
I don't see anything that this guy is doing that is wrong. He is new at this, but he is communicating what he wants directly and asking for what his partner wants.
What exactly is the problem here? Other than a general dislike of sexuality, why are people being so hostile?
