Is sex outdoor allowed in islam?

Dear anyone who can help me,
I want to know if certain outdoor practices are allowed with my wife

• sex in car but in empty location (eg-parking lot…) and fully covered
• sex in the backyard or beside the swimming pool area in a private villa or own house as walls are high and private
• creating a tent on an empty beach,land or desert with privacy and performing
• (indoor) having intimacy (at least like kiss and cuddle) whenever staying at (my or her) grand(family) house
  whenever family is staying but done behind locked doors.

thats all for now as i got a doubt about this topic, sorry for asking such question.

(BTW i do not need any narration and inverse answers, only direct with reasonable definition)
and can she wear frock in home or in my outdoor house premises?

jazakallah
