Masturbation

Guys I feel like I'm broken haha

So I'm 19, and I'm not a virgin(its been 2 years) but I'm to insecure to be having sex with someone so I try to help myself.

I have no feeling from fingering myself all I can do is play with my clit... I get this strong feeling as if I'm climaxing but I never orgasim it only lasts a few seconds and then I cant do anything else. But to me it's not enough, but my I feel "sore" after and cant do it more than once. I thought about buying toys but I'm not sure what's best?

The 4 times I've had sex, 2-3 years ago I honestly didnt "feel" anything I just faked the whole time if that makes sense. I always wonder if its because i didnt have a connection with those people, or if medically something is wrong with me.

I just need advice, I want to know if I'm ok and it's just my insecurities stopping me or if theres something wrong, any questions just ask. Thank you.
