The idea is to bond, to connect, to build energy and then transcend. You need a body for that process and go ahead and use all the five senses. Wake up the body, the whole thing. Get to know you partner and what type of touch they like, sounds, smells, tastes and sights.
FIVE SENSES EXERCISES:
How can I arouse each of the five senses?
What happens if I put in ear plugs? Do the other senses heighten?
How do I build trust in conversation prior to doing this during sex?
Same with blindfold.
Make sure you have talked about it and agreed/consented to the sexual behaviors. This is not a time to spring a fetish on your partner or try something he/she might consider “risky”- be super considerate when you are asking them to surrender one of their senses, even temporarily.
Talk about how much time you want to spend doing this and realize that people do not estimate time accurately, so be open to a feedback loop. Literally ask, “How are we doing? Is it okay to keep going?”
If it is going to be a long time, talk about types of lubricant and the need increases as the time increases.
Talk about positions. Kama sutra has plenty of suggestions. With age, some positions are not as easy to do. If there is any challenge with erectile dysfunction, you definitely want to negotiate positions prior to being intimate.
Remember this is the responsibility of both parties. If one person has the total responsibility for sex, most couples find that a bad long term strategy. The person who does more work often gets resentful later on. Find a way to share the load.
