I have a hot girlfriend. We love each other very much and she is my best friend. I trust her 1000%. I am a 28 year old regular straight dude and I have done a decent amount in my life / I have a decent amount of experience dating and being with girls.

Sometimes when she talks about sex in her past or she posts pics of herself looking hot on Instagram or social it gives me this “uncomfortable feeling” where I may shutdown or withdrawal from her temporarily. Basically I feel like she has this “girls gone wild” side of her that I don’t necessarily understand. She’s definitely dated a lot more people then I have and has more experience than me.

I know I may struggle with confidence sometimes. I want to know if other guys feel this way with hot girlfriends?
