Sexless relationship

I don’t know who to talk to about this because I feel embarrassed :/.
Male (32) dating a Female (30) we’ve been dating for 5 years. Overall she’s great, friends like her, patents lover her, I get along with her family too. Everything looks good on paper for the most part. Except for the one thing, the lack of intimacy, the lack of desire. I’ve spoken with my partner about this and this is when she opened up to me about penetration being painful for her. I’ve tried taking this slow, using lube, foreplay I even bought a vibrator for her as I thought it would be fun to use her on her to bring some spice into the bedroom. It helped a little bit but she’s developed such a fear towards penetration because of pain that she’s basically completely shut down. Which has lead me to feel more like roommates with my gf than I do as a couple. I’ve noticed that this has slowly eroded our relationship.

I’ve continued to make sure I keep myself in shape, dress nice and overall trying to keep myself attractive hoping she will want me… but because of everything I keep getting rejected over and over. I miss feeling the desire of my partner wanting and needing me.. where I’ve noticed being out in public other females smiling and complimenting me feels great.

I’m scared that things will never change and I will be a middle aged man stuck in the same loop
