Can we use both male condoms and female condoms at once?

No: It is not a good idea to use male and female condoms together. Friction between the 2 increases the risk of tears and of condom failure.It would be safer to use another method of contraception with the male condoms. This includes spermacides which are frequently used with male condoms. Hope this helps.
