I can't orgasm with my boyfriend

Andrea

He has gone down on me so many times for so long. I can climax but not orgasm. He would finger me, play with my nipples, kiss my neck, he literally does everything to me but I can't seem to orgasm.

When I masturbate I can do it pretty quickly but so far I haven't with my boyfriend. I feel so bad.

Please give me advice or tips, any thing helps .
