Telling your partner that sex isn't good can be an awkward and difficult conversation, but it's important to communicate honestly and respectfully to improve sexual experiences together. Here are some steps you can take:
Choose the right time and place: Choose a time when you and your partner are relaxed and have privacy. Avoid this discussion during a debate or in public.
Be clear and specific: When talking to your partner, be clear and specific about what you want to address. Be honest, but be careful with your words and try to avoid a tone of conversation that makes him/her guilty. For example, you could say something like, "I feel like we're not completely satisfying each other sexually, and I think we could improve our experiences together."
Be open to listening: Be prepared to listen to your partner's feelings and concerns about the situation. This conversation should be a dialogue where you both express your thoughts and feelings.
Offer solutions: Suggest possible solutions that you think could improve your sexual experiences together. For example, you can try experimenting with new positions, using sex toys, etc.
Focus on the positives, too: Even if the sex hasn't been great, try to focus on the positives in your relationship. Remind your partner that you care about them and want to work together to improve your sexual relationship.
Remember that open communication about sex can lead to stronger and more enjoyable sex.
