How about when you have an erection when you’re watching pornography alone; 4. Whether you have an erection when you get up in the morning and sleep in the middle of the night (asleep to let your lover to help you see); 5, the above are summarized, if none of them, are not, then you should go to the hospital to seek medical advice; if other times, then we have to find out why they can at that time, not when making love, compare the two states, try to make love when you can enter the state. There are many ways to have sex between couples, many techniques, you need to learn and feel for yourself. As an example, during foreplay, you can touch, hug, kiss, tickle each other, lick behind the ears, lips, nipples, belly, vulva, inner thighs and what not.
