Sorry I haven't had much to say recently; a couple of thoughts just came up though.
To me, Christianity is true. I see no reasonable alternative explanation for the available historical accounts other than the resurrection of Jesus. And this forces me to accept things I don't much like, like abstention from sex outside of marriage.
Recently, though, this one has been getting easier; I've been seeing a few reasons to prefer the idea of marriage, or at least a long relationship, before sex.
One is some dommes. The Web is full of nasty, predatory, morally ugly dommes. Looking for porn for my submissive side exposes me to buckets of these. They drip with contempt for their subs, and I am revolted by that. (Note, in their defense, this is apparently what sells best.) I don't want contempt, so I don't want to share my submissive side, other than in this pseudonymous intellectual sense, with anyone I can't trust deeply.
And the other is closely related. It's the stigma of being a male and enjoying submissive play. As far as I can tell, submissive women have it much worse because they are "reinforcing the patriarchy" and "betraying feminism". For a man, though, it's still an insult to imply that he wants submissive sex. And again, that makes me only want to share with the right person.
Other people have already talked about the contempt and stigma and said pretty much everything I'd have to say about it in itself; I only had this little to add about the effect.
