To answer your question. "Is it daddy issues?" NO it's NOT!

She was 18 and 22 in different relationships trying out different things and following the course of relationships as many couples would do.

It sounds to me like you are withholding her from giving you oral sex just to make a point. I don't believe withholding things in the bedroom in order to put your foot down serves anyone well.

I can't really comment on why they didn't give her bday/ christmas presents as there could have been a number of reasons, including working or still at school at that age with no money. Think of it this way - it's great they weren't buying her gifts to have sex with her or get oral sex in return!

If you don't get over your issue with the fact that she had past relationships prior to meeting you it's going to damage and eat away at your current relationship.
