Here are some key points that I would advise you to concentrate on

• All through your life, you create experiences and a unique skill-set, that you can use for a better job, to be creative and give back to the world. 
• Life offers a lot of moments where it offers you a chance to change, to start again, try something new, or chase your dreams, you just need to take the chance, not to hold onto the comfort zone or the painful life as it’s not that painful enough to leave yet. Go for it.
• Your attitude to sex determines how you will have sex and the partners you will attract.  
• You should not be ashamed of what attracts you, what you want to try in bed, but remember consent and communication! You need to discuss it, seek consent, connect and remember consent can be removed at any time. Be open to new ideas, suggest and be mature enough to accept a no, or not right now reply. Communicate before, during and after, as you grow sexually and even as a couple. Let her or him or them, explore themselves, try new things, and grow in bed and as a person.   
• If you struggling with performance anxiety, premature ejaculation etc, don’t beat yourself up. Their are methods that can help such as edging, and perhaps even medication if required. Never beat yourself up or feel worthless, you just need to find the tools and methods to fix the issues to get the sex that you want and deserve.
