Recently joined local leisure centre they have four pools in different locations,

(1)they have one men only session and one women only session in pool which is not near my home.

(2)In the pool near me they don't have men only sessions and they have three women only sessions!

(3) pool three has two women only sessions.

(4)Pool four has two women only sessions and no men only sessions.

Of course most of the time the pools are mixed use they also have times for people over 60 and children.

I feel this female and male only should not exist and if it must it should be even for each gender.
