I’m the only person who he’s been with where he’s needed “help”

So I’ve been dating my fiancé for four years now. He’s admitted to having sex with over 80 girls.. he’s also admitted that I’m the only person he’s ever need to take tablets with the get help to meet my needs sexually.

Apparently it’s all for me, to meet my need but I feel like if he’s capable to sleep with 80 women then why doesn’t he need to take anything with his own gf/finance? I feel like maybe he’s not as sexually attracted

Today we were playing a card game with our friends and I

Found out that he’s had sex in the back of a car, on the beach, I’m a portacot… etc. whenever I try to be adventurous with him he never wants to!! What is going on?!
