They told you not sweat the scale right? Muscle is a fair bit heavier than fat. You may actually go up in scale weight at the same time you go down in pants size. Plus your legs, back and shoulders may fill out some too. Lotta beef. It will add scale weight but good scale weight.
As you feel stronger and look better it will boost your confidence which can help in feeling better about intimacy. If you start feeling a bit of the swagger, I can guarantee, she will too. Woman know when a man is feeling his own power. She will become more attracted to you. You mark my words on this. Good for you!!!
