Re: Low desire for sex-caused from self image?
Just a couple of thoughts here,
First, The burning could be from friction, if you are apprehensive and lose interest even for a couple seconds the vagina can dry out, try using a lubricant and see if it continues. The others can be right as well if you have an infection it can cause irritation as well, but you would show signs of infection either by discharge, or oder, especially worse after intercourse.
Im going to make a huge assumtion here, your husband is aware of the HPV and is okay with the history, and you are still concerned with it or passing it on, then discuss using a condom, unless you are concidering pregnancy. It may help you relax more if that issue is addressed.
On the lighter side, most newly wed males don't think once a week is enough, I have been married 6 years and trust me, my husband still swears hes the most deprived man on earth, trust me hes far from it......lol
Have just a couple of questions though, are you comfortable with your sex life and basically happy with your "knowledge" and performance? Do you feel that there is something missing on either side, you may need to speak to your husband or someone else you can trust to become more comfortable if you aren't now.
