Insecurity about my sexuality

I feel really insecure about my sex life. I think i would like to be having more sex but my insecurity really gets in the way. Im 26 and i haven't had a lot of sexual partners. When i hear others around me talk about their sex lives I feel critical of myself and even resentful.

I think i find it difficult because I want to pursue more sex but i feel like i cant be myself doing it. Im a 'nice guy' and all i seem to hear is how unattractive that is.

I have been really trying to work on myself recently, particularly trying to appreciate and love who i am as a person so i feel really conflicted. I want to have a sex life but i have had far more success by pretending to be somebody that im not. Im also trying to steer my life away from drugs and alcohol so i cant lean on the edgy guy routine any more. In honesty i think i feel angry which is really uncomfortable for me.

Ive just read this all back and i dont think i come across as a nice person here but im going to share anyway. These are all really uncomfortable feeling for me to sit with and i guess i feel ashamed for feeling them. It would be great to hear if any of you have had similar feelings or experiences. I think at the core of is my fear of rejection but let me know what you think. I hope you all have a great day. Love to you all.
