Gemini will be wonderful lovers. Soft, tender and very attentive, but - terribly vulnerable. Not once you will be in the seventh heaven, but those periods won't be long. Whether your fall from it will be rapid and painful will depend only on your partner's and your wisdom.
Changes of mood, quite typical for Gemini in general, will be especially stormy in mid-summer. If you manage to pass this period without any follies and keep your relations (it does not apply to married Gemini - the thunderstorms probably await them at work), you may consider yourself extremely lucky. Your friends will play a big role during this period, they will help you to go through it without losses.
