Oral Sex

Hey everyone!

My boyfriend and i have been having a lot of Vaginal Sex for ages now, where we both finish in it, but in foreplay have oral sex as well.

Recently i’ve been trying to just have some oral sex to change it up, but my boyfriend can’t cum, as he is so used to the vaginal sex (speed, feeling etc.)

just wondering if anyone has any tips to help possibly help me, to help him finish xoxo

thanks
