New partner and orgasm

Hi

Been with a new partner for quite a few months now, everything is going very well.

Except in the area of her orgasm, she never orgasms through normal sex, though this isnt the first partner ive had like this so assume its not uncommon

However previous partners have always been able to orgasm easily with oral, with my new partner she does orgasm through oral, but it takes a lot of time, buildup and patience. Also after orgasm she is a 'do not touch' zone for a very long time after. Finally, if i give her oral say twice in the same day or two or three days n the trot, she seems to desensitise and it takes forever the third or fourth time.

We are pretty open about it all, and ive always said that if my technique is not her cup of tea my ego would stand being told, but its got me very puzzled as previous partners have never been like this, obviously i love her and want her to enjoy lovemaking as much as i do.

Anyway question is, is anyone else like this?. Or any ideas how i can give her more orgasms without making her tender?. Ive tried gently stimulating her g-spot instead, but she finds that 'too much' and doesnt really like it.

Should add, she doesnt see any problems in this area, we cuddle, kiss lots, make love lots and in her words 'she loves to feel me inside her wether she comes or not'

but obviously, i want to make things better for her...and despite a normal number of previous partners im a bit flummoxed here

Thanks
