Orgasms

So I am a 22 year old female. I have been with 14 men some used condoms some not. I have 0 STDs. For some reason men can not make me cum off of sex.... I have only came 1 time off head and 4 times off fingering.... Cumming off head felt amazing but I did not like Cumming from penetration....Sex feels great i love having sex, but orgasms don’t feel that good to me.... I would rather see my partner nut and call it a day.... is this normal am I the only one out there like this ? Should i be concerned ?
