Sex Buck Naked or With clothes on?

Sooo im trying to find ideas to do some stuff differently in bed with my partner as suggested...and normally I have a habit of only taking pants off during sex...shirt & bra i normally keep on. I HAAAATE showing my stomach 😩 even if it is my partner of a long time, he doesn't mind it, & he's obviously seen me naked before but still I just hate showing it or being fully naked during sex. Tbh I've done this FOR A VERY LONG TIME even with past partners and when I lost my V-card😬. And we already do it in pitch dark bc night time is only time we really can do it. Lights normally stay off as i also usually have a hard time making eye contact anyways (yes another bad habit of mine.) Sooo what can I do to try and lift up out of that habit and be fully naked during sex 🤔? Its already hard for me to feel comfortable during sex. I feel more tense...with my eyes shut 90% of the time...when I know it should be the opposite
