Hi there vidalevi,
After reading your post, the thing that stood out for me was that even though you are in your thirties, you mention how you have the look of a high schooler. Embrace it. It means that as you age you will continue to look young and have that presence of youth. Just as you said you are capturing the attention of men around campus who have noticed you. Don’t worry chances are they are just as nervous as you are. If there is a guy that you find eye catching, then start things slow and message him through social media. Don’t be afraid to make the 1st move. What’s the worst that could happen, he does not reply to you. You did not know him before so why should it matter afterwards.
Thank you and take care
