How to have intimacy longer? we last only 30 mins.. and he is very unhappy in a way he comes first and then i do what can we do?

Intimacy: Regarding your partner's unhappiness, why not take turns on "who comes first"? Simultaneous orgasm is a rare thing for both heterosexual and homosexual couples, in real life. As for "intimacy": this depends on being yourself in the moment, allowing the other to see you as you are -- and can last long after you have both climaxed. Erections can also rise again, after varying refractory periods.
