I don't know anything about the sexual culture in your country, TryingStill. In the United States, being on top is the preferred position of many women. They feel it improves their ability to orgasm because the position allows better clitoral stimulation during penile penetration than some of the other positions. Some women don't like it because they feel more self-conscious about their bodies in that position. In the USA, many men seem to prefer to have the woman astride them during intercourse. It can bring pleasure to both sexes.

If you like it and if the woman you are with likes it, then all is good.

In general, for both parties to feel comfortable and satisfied by the encounter it's important to learn to talk openly, honestly and kindly to your partner about what positions and activities you both want to engage in and what brings you both pleasure. That, more than anything else, will contribute to you being a good lover.

I am glad you have been able to resume sexual activity after your recent surgery. I wish you the best.
