An NHS-backed safer sex guide for women who sleep with women will leave many readers scratching their heads over its advice to wear a condom, ‘if you or your partner has a penis’.

The mind-boggling advice comes in a booklet produced by LGBT Youth Scotland in a section on ‘Contraception and safer sex tools’.

The publication is endorsed by NHS Greater Glasgow and Clyde, which said the condom advice related to transgender women who may still have male genitalia.

The guidance in the booklet – entitled ‘Good Sex Is... For Women Who Have Sex With Women’ – states, ‘if either you or your partner has a penis then you should always use a condom’ to avoid becoming pregnant.

Last night, lesbian feminist Linda Bellos, a veteran campaigner for women’s and gay rights, said it was ‘ludicrous’ to suggest ‘women’ have penises.

Ms Bellos said: ‘This guide is not only foolish but as far as I’m concerned, it’s downright dangerous and anti-lesbian.

It’s not been very long since lesbians had any kind of social recognition. We are always being erased and this is another example of our erasure.

‘It’s belittling our history that now men are claiming they are lesbians. If they are encouraging lesbians to have sex with men then, as far as I’m concerned, that is being heterosexual.’

A spokesman for NHS Greater Glasgow and Clyde said: ‘Trans-women who may still have male genitalia or intersex people who may have genitalia that does not fit their self-defined identity do have relationships with other women.’
