Lesbian sex basics...
There's no golden rule of lesbian sex, any more than there is with straight sex. Everyone has their own desires. However, understanding the basics will help ensure you have the most satisfying time ever.
Every woman is different. Some like manual stimulation, some find oral the most satisfying, some like toys (including strap ons), some like it all. Just because you like something, it doesn't mean a partner will so communicate and explore together.
Oral transmission of Sexually Transmitted Infections (STIs) are on the increase, so use a dental dam (latex square) to stay safe unless you've both been tested. STIs can be transmitted through sharing toys too so use condoms if you share.
There's no need for safe sex to be boring. Try ribbed, dotted and other sensation-changing condoms on toys to ring the changes. Dams are available in different flavours as well as plain varieties too.
Try using a pleasure ring on a dildo to add clitoral stimulation. Use a bullet vibe during oral or simply dress up for each other. Ring the changes to keep things fresh.
