okay so I just had a baby 3 months ago me and s/o have had sex only twice once at 9 weeks postpartum and yesterday morning the first time he pulled out and finished in his hand I saw it and started full on gagging at the sight of it I don't know why and yesterday morning he finished on me and again I immediately started to gag nearly throwing up what is wrong with me do I have a phobia of semen wtf there were no problems before or during pregnancy so does anyone have any insight as to why I'm gagging at the sight and feel of my s/o's semen I'm scared it will turn him off from wanting to have sex 🤤😭
