Orgasm tips?! 🎀

Any ways in which it makes it easier to orgasm by having sex (any form apart from anal). Been sexually active for over 3 years, - don't masturbate- always have foreplay or oral with my partner and nothing ever makes me reach it. I understand it may be difficult for some but I'm losing my hope😔
He doesn't usually last very long as well which I guess doesn't help.. 
Any tips would be perfect!Â
