I am 45 and sexually active, but cant really tell what is normal anymore. I have had occasional bouts of ED, mainly with a new partner, so I assume it is mainly Performance Anxiety. What bothers me is that when my girlfriend wants to be on top, I have trouble staying hard....it seems like my body position has a lot to do with how hard I am. Starting sex from the bottom is almost impossible. When I am on top and inside her, there is rarely a problem and I can go for a long time. The other problem is oral sex. Most of the women I have been with have made me feel like it was a chore, so I guess I have a guilt complex about it and find it very hard to stay hard during oral sex. My current girlfriend loves it and is VERY good at it, so Im a bit perplexed. Anyone had a similar experience or think that Viagra will help the "problem on the bottom" situation or the inability to stay really hard during oral sex..
