Is it normal that i feel this like this?

Me and my girlfriend have been dating for 4 months, we love eachother, but her past isn't very nice. I know I can't judge but truth is I'm so jealous. She hasn't slept with that many people but the worst part and the parts I hate is that she has had two one night stands and was a booty call before about 5 times for one guy. When I met her I hardly even slept with anyone only 2 girls. My outlook is completely different than hers, now when I have sex with her I feel super inadequate I feel like I'm just another guy. She's even told me that I have no real traits she likes such as looks or values she has( we are both asian, her family is very traditional and are fluent in our language but I cannot speak it) but anyway I feel like she'd give herself away to anyone I'm nothing special, I know her ex has a bigger Dick than me what makes me any more anything? her ex got it all he played with her he had a bigger Dick, he was the one that was her booty call he even got to try anal with her (on one of the one night stands) he had looks which I was stupid and asked and she told me the truth about him looking better than me. I just feel like I'm just a random stick she picked off the ground nothing special nothing she was looking for. When we have sex i feel like its special like were doing something for eachother because we love eachother we get to explore eachothers bodies we get to conncect on a different level but I asked her if there's anything different between me and other guys she was quiet because we both know there's nothing different. I'm nothing different. I'm just another guy. She says she loves me, I know she does. But at the same time, I know ill never be the best. Ill never be something special. I'm just a random stick. Don't ask if I talked to her about it of course I have she just sits quietly and it pisses me off.
