Been dating a girl for about two years, so not a fresh relationship (though not long relative to you all). Some background: we're both in our twenties, she's a conservative girl relative to the modern day female. She makes bracelets and photo frames for me, and enjoys simple relaxing dates. She's in it for the long run, and wants to get married.

Now to the topic: I've noticed the type of sex position affects her behavior outside of the bedroom.

When we have sex, we're wild in the bedroom but 'sweet', 'modest' and not much PDA outside of the bedroom. When I sex her doggie style (and specifically this position), its wild in the bedroom but she seems to carry that 'lust' or 'wildness' outside the bedroom as well (ex: in streets). In general she's a lot more hormonal and short-tempered.

Granted I've made her orgasm both through doggie and other positions, so I doubt that its simply because the sex is 'better'. I genuinely feel that position messes with her brain.

Was wondering if you guys have experienced similar?

EDIT: I've read the 'sex god method' and I incorporate that in all positions. I do nothing different during doggie, but it messes her up.
