I have been trying to walk the fine line between growing boobs and functional. With my relationship, I have to make my sexual performance higher priority. Growth is certainly slowed, but slow growth is still possible.
Here is my advice:
1. Keep using it, we have sex almost daily.
2. Jelqing and pumping to maintain size ( I do this at the same time I noogle, usually daily )
3. I use white peony and saw palmetto to block DHT - these seem to have least impact on my libido.
4. I do topical PM / Estrogen on my chest, hips, and inner thighs, and avoid use on the penis and testicles. I tried it for a bit and it completely killed my libido in two days.
5. I use estrogen & PM for a few weeks then, add progesterone seems to improve my libido and function for a while.
6. Strenuous exercise - I lift weights hard, run, and do sprints. Things go south quickly when I am taking estrogen and don't exercise.
7. Take recovery breaks. I can go months before things go south. When that happens, I stop until I recover my function ( which is usually within a couple weeks )
Although counter-intuitive - I have also tried applying estrogen 30 minutes before sex and the sex has been great (is it just psychological?). Plus what everyone else has said.... VIAGRA
The look, feel, color and sensitivity down there have changed quite a bit over the past few years. Light stimulation does more for me than stroking now and nipple orgasms are much more common. I do find orgasms both more intense and enjoyable.
