Have you ever felt guilt or shame because of sex or masturbation?

Have you sometimes felt guilt or shame because of sex or masturbation? What reasons or circumstances were involved?

Were you ashamed afterwards for having sex with a specific person, or at a very early stage of dating, or as a one-night stand?

Were you ashamed that the objects of your sexual interest were perhaps objectionable in the opinion of other people? What were these objects of interest?

Or is it so that nothing related to sex has ever caused you remarkable guilt or shame?

If you mention your gender, that would be great.
