Hi lydiap – this is very normal! For partners who have not had a lot of sexual experience or who are getting an opportunity to have intercourse after a long break, the experience can often be so overwhelming that they ejaculate prematurely.It’s inconvenient for you but definitely fixable. Could you have your partner masturbate perhaps earlier in the day when you plan to have sex (maybe a couple of hours before) so he has more stamina for when the moment for actual intercourse comes? See if this helps!
