Orgasms

Hi I’m new to this site but everybody seems really friendly and happy to help, iv never had sex with anybody before, I have messed around but it has always stopped before sex because I don’t seem to have much feeling down there, so when they finger me or give me oral I normally have to fake it has I just can’t seem to orgasm even when I try to cum by myself nothing happens. I’ve tried my own fingers, toys and orgasm gels but still nothing. Has anybody got any suggestions of what I can do to help myself as I really want to have sex and enjoy it without the stress of thinking that I have to fake something. Thank you so much. Xx
