So i have a little confusion going on in my head. I been in a LTR for about 5 years now and have always had an insecurity of my gf cheating from time to time. Main reason is because of instances like recent. The other day we were having sex and when i first entered her it really didnt feel like much. She was on top and going a bit hard and i could barely feel any friction. After switching positions and busting inside of her she was really wet and her pussy was open to the point that i can slide in & out with no prob. Now i've been reading about porn addiction, masturbating leading to less sensitivity and less arousal levels and hopefully this is what my issue is but my question to the forum is, what's your opinion on cheating? Do you think my particular situation where i entered my gf easily in the beginning of sex and didnt feel much was due to someone else that was bigger than me already entering and expanding the walls prior to me entering her (my gf is usually tight & dry, making it a lil difficult to enter at first) or was it because i masturbated earlier that morning?

That's quite an elaborate cheating accusation haha.

Maybe she was more in the mood than usual and you were less in the mood than usual. Don't worry about it.

Maybe she secretly had a baby that you don't know off??

I think you are overreacting/overthinking.
You are fine.

Sounds to me like you got a little insecurity goin' on. But the vagina expands and gets more moist with arousal. If she's usually dry and tight, it more likely means that she was more turned on than usual if you did that. If you had a bit more foreplay goin' on, then she'll be more aroused, so that might've been it. And if you yanked it earlier that day, than yeah, that might've effected it quite a bit too.

I'd recommend working on your confidence and trust a bit more, though. If you found used condoms on your guys' bed that you don't think you used or whatever, than yeah, okay, but you're over-thinking this shit, man.

Yea i do admit that i have insecurities and she doesnt help with them sometimes!!! Lol but i needed another POV to make myself feel better. Thanks guys
